Heat Transport and Effective Landau Fermi Liquid Parameters in Disordered Interacting Electronic Systems

摘要

The renormalization of the specific heat and of the thermal diffusion coefficient due to the electron-electron interaction in the presence of disorder, is determined by exploiting the skeleton structure of the heat response function in conjunction with the constraints originating from energy conservation (in the form of a Ward identity). This analysis leads to a generalization of the Wiedemann-Franz law near the localization transition with inclusion of interaction effects.
