Renormalization Group Approach to Quasi-One Dimensional Systems
Samuel Moukouri
Equipe 106, Institut Jean Lamour
mercredi 14 mars 2012 , 10h25
Salle de séminaire du groupe de Physique Statistique

The advent of high performance computing and the development of sophisticated numerical techniques have opened new vistas for researchers in condensed matter physics. Exciting predictions of new quantum phases of matter in model systems can often be substantiated or falsified by numerical methods. In this talk, I will present recent development in applying the celebrated density-matrix renormalization–group method to quasi-one dimensional systems. I will show the power of this technique by computing, with high accuracy, critical points in quantum phase transitions induced by small inter-chain interactions. Illustrations are made on models for magnetic frustration and for the Mott transition.
