 Out-of-equilibrium properties of the semi-infinite kinetic spherical model. Baumann F., Pleimling M. Journal of Physics A: Mathematical and General 39 (2006) 1981-1999 DOI : 10.1088/0305-4470/39/9/001 ArXiv : cond-mat/0509064 [PDF] We study the ageing properties of the semi-infinite kinetic spherical model at the critical point and in the ordered low-temperature phase, both for Dirichlet and Neumann boundary conditions. The surface fluctuation-dissipation ratio and the scaling functions of two-time surface correlation and response functions are determined explicitly in the dynamical scaling regime. In the low-temperature phase our results show that for the case of Dirichlet boundary conditions the value of the non-equilibrium surface exponent $b_1$ differs from the usual bulk value of systems undergoing phase ordering.
