Non Perturbative Renormalization Group and the KardarParisiZhang equation 
The Non Perturbative Renormalization Group (NPRG) is by now a well
established and widly tested
method thanks to which several results unreachable by perturbative means
have been obtained
for systems either at or out of thermal equilibrium. We review the
method and show how NPRG
allows us to obtain the full phase diagram of the KardarParisiZhang
equation in all dimensions
including the fixed point describing the strong coupling (rough phase)
with exponents in reasonable agreement
with numerical ones.

Current fluctuations in non equilibrium systems 
This talk will present a series of recent results on the fluctuations
of the current in nonequilibrium diffusive systems.
When the system is maintained in a nonequilibrium steady state by contact
with two reservoirs at unequal densities, the fluctuations of the current
have in general a nonGaussian distribution which can be computed exactly
for diffusive systems [1,2,3].
For systems at equilibrium on a ring geometry, the cumulants of these
fluctuations take a universal scaling form which can be understood
by several theoretical approaches such as the Bethe ansatz or fluctuating
hydrodynamics [4].
Some recent results concerning non steady state initial conditions will
also be discussed [5].

Examples of a Grassmann technique applied to classical spin systems in 2D 
In this talk, we will present an analytical method using Grassmann techniques to study the fermionic theory underlying general spinS Ising models in two dimensions. The simplest case S=1/2 was understood a long time ago and is known to be equivalent to a massive free fermion theory possessing a secondorder transition when the mass vanishes. Here we try to extend the method for general spinS with the additional presence of a splitting field in the Hamiltonian. One of our motivation comes from the fact that there is little knowledge about the fermionic theory of such models and the relation to the free fermion theory of the S=1/2 2D Ising model. In particular we can show that the BlumeCapel model can be exactly mapped onto an interacting fermion model, with a bare mass depending on the value of the splitting field. The location of the points that make this bare mass vanish is very close to the numerical results found by MonteCarlo method in the region of the secondorder transition. The extension to spinS models and a method to find the bare mass in general is presented, with an accuracy of less than 1% for the secondorder transition lines in these models. The particular values of the transition points at zero splitting field are then compared to high and lowtemperature expansions.

Nonequilibrium dynamics of fully frustrated Ising models at T=0 
We consider two fully frustrated Ising models: the antiferromagnetic triangular model in a field of strength, $h=H T k_B$, as well as
the Villain model on the square lattice. After a quench from a disordered initial state to $T=0$ we study the nonequilibrium dynamics
of both models by Monte Carlo simulations. In a finite system of linear size, $L$, we define and measure sample dependent relaxation time, $t_r$, which is the number of Monte Carlo steps until the energy is relaxed to the groundstate value. The distribution of $t_r$, in particular its mean value, $\langle t_r(L) \rangle$, is shown to obey the scaling
relation, $\langle t_r(L) \rangle \sim L^2 \ln(L/L_0)$, for both models. Scaling of the autocorrelation function of the antiferromagnetic triangular model is shown to involve logarithmic corrections, both at $H=0$ and at the fieldinduced KosterlitzThouless transition, however the autocorrelation exponent is found to be $H$ dependent.

Fractals meet Fractals: SelfAvoiding Random Walks on Percolation Clusters 
We consider selfavoiding walks (SAWs) on the backbone of percolation
clusters in space dimensions $d=2, 3, 4$. Applying numerical simulations
based on the PERM chaingrowth algorithm, we estimate the critical SAW
exponents and show that the whole multifractal spectrum of singularities
emerges in exploring the peculiarities of the model. We obtain estimates
for the set of critical exponents, that govern scaling laws of higher
moments of the distribution of percolation cluster sites visited by SAWs,
in a good correspondence with an appropriately summed fieldtheoretical
$\varepsilon=6d$expansion.

Qantum NonEquilibrium Steady States Induced by Repeated Interactions 
We study the steady state properties of a finite XY chain coupled at its boundaries to quantum reservoirs. The reservoirs are made of free spins that interact one after the other with the boundary sites of the chain. We show that the dynamical equations governing the time evolution of the twopoint correlation matrix are of Lindblad type in the continuous interaction limit. Under XY coupling with the reservoir spins, the steady state correlations are calculated exactly. It is shown that the relevant physical quantities characterizing completely the steady state are the magnetization profile and the associated current. Except at the boundary sites, the magnetization is equal to the average of the reservoirs magnetizations. The steady state current, proportional to the difference in the reservoirs magnetizations, shows a nonmonotonous behavior with respect to the systemreservoir coupling strength, with an optimal current state for a finite value of the coupling. Finally, the steady state density matrix is shown to be of generalized Gibbs form. At small current linear irreversible thermodynamics predictions are recovered.

The SiteDiluted Ising Model in Two and Four Dimensions 
The Ising model with uncorrelated, quenched randomsite or randombond disorder has been controversial in both two and four dimensions.
In these dimensions, the leading exponent $\alpha$, which characterizes the specificheat critical behaviour, vanishes and
no Harris prediction for the consequences of quenched disorder can be made.
In the twodimensional case, the controversy is between the strong universality hypothesis
which maintains that the leading critical exponents remain the same as in the pure case and the weak universality
hypothesis, which favours dilutiondependent leading critical exponents.
In the fourdimensional case unusual corrections to scaling characterize the model, and the precise nature of these corrections has been debated.
Here both versions of the model are subject to finitesize scaling analyses, paying special attention to the implications for multiplicative logarithmic corrections.
The analysis is fully supportive of the scaling relations for logarithmic corrections and of the strong scaling hypothesis in the 2D case.
Progress is also made in determining the correct 4D scenario.

Depinning transition for domain walls with an internal degree of freedom 
We examine the dynamics of a domain wall subject to a pinning potential, in situations where the position of the wall is coupled to an internal degree of freedom (e.g. a spin phase, in magnetic domain walls). We investigate the corresponding depinning transition, which displays several novel features when compared to standard cases. At zero temperature, there exists a bistable regime for low forces, with a logarithmic behavior close to the transition. For weak pinning, there occurs a succession of bistable transitions corresponding to different modes of the phase evolution, separated by topological transitions. At finite temperature, using techniques from stochastic dynamical systems, we show that the forcevelocity characteristics is nonmonotonous, as an effect of the zerotemperature topological transitions.

Mach Zehnder spin interferometer for Rashba and Dresselhaus media: Exact solutions for perfect spin filtering 
We address spin filtering through quantum spin interference in a medium that has both Rashba and Dresselhaus spinorbit couplings. We propose an experimentally feasible electronic Mach Zehnder Interferometer and solve for the perfect spin filtering conditions. We find two broad solutions, one where filtering is achieved in the original incoming basis that is purely a nonAbelian solution, and the other where one needs a tilted axis to observe the polarized output spinor. Both solutions apply for arbitrary incoming polarization, and are only limited by the randomness of the incoming spinor state.

Chiral Electron Transport: Scattering Through Helical Potentials 
We present a model for the transmission of spinpolarized electrons through oriented chiral molecules, where the chiral structure is represented by a helix. The scattering potential contains a confining term and a spinorbit contribution that is responsible for the spindependent scattering of the electrons by the
molecular target. The differential scattering crosssection is calculated for right and lefthanded helices and for arbitrary electron spin polarizations. We apply our model to explain chiral effects in the intensity of photoemitted polarized electrons transmitted through thin organic layers. These are
spinactive molecular interfaces that exhibit electron dichroism and a number of remarkable magnetic properties. In our model, differences in intensity are generated by the preferential transmission of electron beams whose polarization is oriented in the same direction as the sense of advance of the helix.

Dynamics of random systems : strong disorder renormalization approach 
To understand the nonequilibrium dynamics of random systems, we will describe a strong disorder renormalization procedure in configuration space, that we define for any master equation with transitions rates $W ({\cal C} \to {\cal C}')$ between configurations. The idea is to eliminate iteratively the configuration with the highest exit rate $W_{out} ({\cal C})= \sum_{{\cal C}'} W ({\cal C} \to {\cal C}')$ to obtain renormalized transition rates between the remaining configurations. The multiplicative structure of the new generated transition rates suggests that, for a very broad class of disordered systems, the distribution of renormalized exit barriers defined as $B_{out} ({\cal C}) \equiv  \ln W_{out}({\cal C})$ will become broader and broader upon iteration, so that the strong disorder renormalization procedure should become asymptotically exact at large time scales. As an example of application, we have checked numerically this scenario for the nonequilibrium dynamics of a directed polymer in a two dimensional random medium.

Emergence of Generic Mixed Phases in RoksharKivelson Models 
The phase diagram of RokhsarKivelson models, which are used in fields such as superconductivity, frustrated magnetism, cold bosons, and the physics of Josephson junction arrays, is revisited. From an extended height effective theory, we show that one of two simple generic phase diagrams contains a mixed phase that interpolates continuously between columnar and plaquette states.
Applied to the square lattice frustrated Heisenberg antiferromagnet, we have extended the RokhsarKivelson (RK) loopexpansion to derive a generalized Quantum Dimer Model containing only connected terms up to arbitrary order. Our results suggest that the Heisenberg model is a physical realization of such a mixed phase, in the parameter region of maximum frustration.

Electronic structure of advanced materials using spacially resolvec photoemission 
Microscopy of photoemission SPEM (Scanning PhotoEmission Microscope) is a powerful characterization technique of heterogeneous systems using the photoelectric effect, i.e. the generation of electrons by a system subjected to an electromagnetic radiation. Contrary to the PEEM microscopy, where the image is obtained by collecting the photoelectrons through an electronic column of optics, the imagery here is generated by a simple nanometer sweeping of the samples and focusing the incident light. ANTARES is one of the first beamlines in Europe that is attempting to extend such demanding technique to the low energy domain, where the states of the valence band can be detected with high precision as well as their dispersions using angle resolved photoemission (ARPES). The objective is to be able to determine the electronic band structure and the Fermi surface together with the chemical shift core level of light elements of advanced materials with a nanometer spatial resolution. The possibility of achieving synchrotron light beams from a few tens of nm to some µm, makes possible the visualization of density of states, chemical heterogeneities likewise magnetic order distributions getting the cartography of the samples on the basis of contrast produced by the photoemission response. This setup is being outfitted with several absorption detectors in order to complementarily obtain, in situ, the imagery based on the absorption contract.
The SPEM microscope at ANTARES beamline will operate in two alternative modes, the imagery and the spectroscopy. In the first mode, the material will be monitored using a synchronized sweeping of the sample with regard to the focused beam, by simultaneously detecting photoelectrons with a given kinetic energy. The second mode allows the determination of the photoemission and absorption spectra at a selected nanometer portion of the sample. I will give several examples of Scanning XRay microscopic studies of a range of heterogeneous systems with applications mainly in corrosion, heterogeneous chemical and structural aggregates and massive systems as well as the growth of metals and characterization of catalysts. Finally, an overview of the utilization limits of the xray microscopes will be detailed together with the future developments based on the last generation of detectors and new focalization optics.

DECAY OF EXCITED ELECTRONS IN SURFACE STRUCTURES 
Interaction between lattice and electron subsystems as well as interaction within each of these subsystems is crucial to understand mechanism of singleparticle excitation dynamics, i.e. lifetime of excitations. The lifetime sets the duration of excitation and in combination with the velocity determines the mean free path, a measure of influence of the excitation. Interest to the study of excited particles dynamics is motivated by an important role that excited electrons and holes play in many processes, e.g. in energy and charge transfer in bulk materials, at surfaces, across interfaces, and at nanosystems.
In this presentation I discuss recent theoretical results on the decay of excited electrons and holes at clean metal surfaces, at single adatoms, at islands as well as at overlayers and free standing thin films. Different decay mechanisms and different kinds of interactions  elastic and inelastic electron
electron (ee) interaction as well as electronphonon (eph) interaction  are analysed. Eph decay channel is shown to be important for all systems considered. In the ee decay channel the electron (hole) decay can be realized via creation of electronhole pairs or plasmon excitation. Dimensionality effects in the lifetime of electrons and holes on metal surfaces and the role of screening and intra (inter) band transitions are also discussed.

Surface state confinement imposed by a supramolecular porous network: Band formation from coupled quantum dots 
The properties of crystalline solids can to a large extent be derived from the scale and dimensionality of periodic arrays of coupled quantum systems like atoms and molecules. Periodic quantum confinement in two dimensions has been elusive on surfaces mainly because of the challenge to produce regular nanopatterned structures capable of trapping electronic states. The practical implementation of this type of confinement will be shown by demonstrating that the two dimensional free electron gas of the Cu(111) surface state can be trapped within the pores of an organic nanoporous network. The confinement units can be regarded as a regular array of quantum dots. Moreover, a shallow dispersive electronic band structure is formed, which is indicative of electronic coupling between neighbouring pore states.

On kinks and waterfalls in ARPES 
Angle resolved photoemission spectroscopy (ARPES) allows to reveal a regime change in the momentum dependence of low energy fermionic excitations, as the distance from the Fermi surface increases. From gentle dispersion crossovers in most systems, more accentuated "kinks" or even "waterfalls", i.e.: discontinuities as function of k  k_F, have been observed. They are attributed to the presence of strong correlations among the fermions or strong electronlattice coupling. I shall present the simplest generic model for a complex selfenergy function that allows to classify such phenomena and analyse the ARPES data quantitatively. The main driving parameter is the ratio of coherent spectral weight over total low energy weight, including the incoherent part. Further, I shall discuss the influence of asymmetry between particle and holelike excitations and, time permitting, the evolution of "kinks" as function of temperature.

Temperature dependence of the exciton condensate phase in 1TTiSe2 
At the temperature of 200K, the quasitwodimensional system 1TTiSe2 undergoes a phase transition towards a charge density wave (CDW) phase, which is accompanied by a periodic lattice distortion (PLD) [1].
We propose the exciton condensate phase model as the purely electronic origin of the CDW phase of 1TTiSe2 [2,3]. Measured angleresolved photoemission spectroscopy data are compared with photoemission intensity maps generated by the spectral function within this model [4,5]. We also discuss features of the model which allow extracting from the experiment the temperature dependence of the corresponding order parameter. Finally, we show recent results on the coupling of the exciton condensate to the lattice, which demonstrate that the presence of condensed excitons are capable of producing the observed PLD.

Investigating Shockley surface states in curved noble metal surfaces: interplay between structure and electronic states 
Vicinal surfaces with periodic arrays of steps and terraces are among the simplest lateral nanostructures. They are useful as growth templates for selfassembled arrays of nanostructures, but also attractive playgrounds for testing the fundamental properties of electrons at one or twodimensional (1D or 2D) superlattices. The most studied case is that of vicinal noble metal surfaces, where repulsive scattering gives rise to a rich surface electronic structure and phenomena that depend on the terrace size (lattice constant) d. On the one hand, the Shockleylike surface state that characterizes these surfaces is observed to evolve from a quasi1D state to a 2D band as a function of d. On the other hand, surface states are characterized by relatively large (1540AA) Fermi wavelengths in noble metal surfaces, and hence may exhibit 1D Fermi surface nesting with reciprocal lattice vectors pi/d. In the latter case, the question arises whether a charge density wave (CDW)like, structural/electronic interplay occurs, i.e., whether such Fermi surface nesting and subsequent Fermi gap opening triggers structural instabilities in the step superlattice.
We use curved crystals to investigate the evolution of surface states as a function of d, namely the miscut angle (alpha) in a single sample. In particular we utilize Au and Cu curved surfaces that cover a alpha=+15° range of miscuts around the [111] direction (alpha=0°). The local structure is determined by Scanning Tunneling Microscopy (STM), whereas surface bands are mapped locally for each miscut angle by Angle Resolved Photoemission (ARPES) by scanning a 100 mum synchrotron light spot.

Modifing the Rashba Splitting of Metallic Surface States 
This talk will summarize recent experiments by photoemission spectroscopy (ARUPS) on metallic surfaces, that reveal a considerable Rashba splitting as a consequence of the changed local symmetry at the surface. The splitting is due to the spinorbit coupling of the contributing electronic states and depends strongly on the atomic composition of the surface, as e.g. in a surface alloy. It shall be discussed, how these states depend on surface modifications as induced by electron doping, local geometry, or by the coverage with a dielectric overlayer.

Angle resolved electronic structure of electrondoped SrTiO3: new hints for old puzzles 
SrTiO3 is considered the cornerstone of oxide electronics. It is often used as a substrate for thinfilm growth of other transitionmetal oxides, and is the preferred template to create novel 2D phases of electron matter at oxide interfaces. SrTiO3 is also a model system for stronglycorrelated electron physics: upon electrondoping the Ti 3d band, it goes from a band insulator to a correlated metal, and turns into a MottHubbard insulator when all the Sr is substituted by La. However, despite the technological and fundamental importance of this material, key questions as the precise experimental determination of its momentumresolved band structure and Fermi surface remain unsolved. Indeed, the electronic structure near the Fermi level (EF) of doped SrTiO3 is not that of a doped band insulator: besides the appearance of coherent states at EF, a broad peak of incoherent states centred at about 1.3 eV forms in its bandgap. These ingap states, obviously not explained by a rigid shift of the bands with increasing doping, are observed already at dopings as low as x ~ 0.05 (about 1 electron every 20 unit cells), where electron correlations are expected to be small. Thus, they cannot correspond either to precursors of the “lower Hubbard band” of the d1 insulator. The nature of these ingap states has also been a longstanding puzzle in the physics of SrTiO3.
Using angleresolved photoemission spectroscopy (ARPES) we have studied in detail the electronic structure of SrTiO3 doped with oxygen vacancies. We determined that the Fermi surface, centred at Gamma, is composed of a central sphericallike sheet surrounded by cigarlike sheets. We observed the degeneracy lift in the conduction band induced by the cubictotetragonal transition occurring at 110°K. Furthermore, we observed that the ingap states do not disperse, indicating that they originate from localized states, rather than from electroncorrelations.

Spectroscopic manifestation of low dimensional physics: a local view 
The interest in nanostructured materials, consisting of building blocks of a small number of atoms or molecules, arises from their promising new optic, catalytic, magnetic and electronic poperties, which are fundamentally different from their macroscopic bulk counterparts: small is different. Here we present selected examples from our laboratory, which elucidate local aspects of physics in low dimensions investigated by photoemission (PES) and by lowtemperature scanning tunneling microscopy (STM) and spectroscopy (STS): Kondo effect of supported magnetic adatoms [13], electronic properties (electron confinement, lifetimes of surface states and of quantum well states, supraconductivity) of ultrathin supported metal islands [48], selfassembly, melting and electronic structure of twodimensional adatom superlattices stabilized by longrange electronic interactions [912], twodimensional supramolecular selfassembly, chirality, and electronic structure of small organic molecules [1317], inelastic tunneling processes leading to vibrational excitations of supported molecules[18] and to local fluorescence and phosphorescence [1921] enabling chemical recognition at the molecular scale.

Quantum size effects in the thin metal films grown on quasicrystalline surfaces 
We have studied the growth and electronic structure of Ag films on 5fold surface of icosahedral (i)AlCuFe quasicrystal using scanning tunneling microscopy (STM), ultraviolet photoemission spectroscopy (UPS) and low energy electron diffraction (LEED). Magic height islands of Ag are observed by STM and these are related to the quantum size effects (QSE). LEED pattern shows that Ag grows in 5fold twinned nanocrystallites with Ag(111) structure for > 7 monolayers and Ag(111) structure is well supported by the UPS spectra of bulklike thick Ag films. Observations of Ag sp quantum well states (QWS) in the UPS spectra of Ag/iAlCuFe confirmed the QSE. Mismatch in the symmetry of electronic states has been attributed to the origin of the QWS.

Tailoring electronic and magnetic properties in structured Au surfaces 
Tailoring electronic and magnetic properties at the nanoscale presents both technological and fundamental interest. Magnetic interactions among nanostructures and confinement conditions for electronic states can be studied in surface systems. Ideal playgrounds to study these aspects are vicinal and faceted surfaces of noble metal surfaces. In these systems, it is possible to induce magnetic stripes and high density magnetic islands lattices by selforganisation. We will show how the lattices influence the nearlyfree Shockley state at the (111) face of noble metals via the modifications of the surface potential. The superposition of the potential of steps and that of magnetic islands leads to a two dimensional lattice of interacting quantum boxes for the surface state.
