Macroscopic Conductivity of Free Fermions in Disordered Media
J. -B. Bru, W. de Siqueira Pedra, C. Hertling
We conclude our analysis of the linear response of charge transport in lattice systems of free fermions subjected to a random potential by deriving general mathematical properties…

Microscopic Conductivity of Lattice Fermions at Equilibrium - Part I: Non-Interacting Particles
J. -B. Bru, W. de Siqueira Pedra, C. Hertling
We consider free lattice fermions subjected to a static bounded potential and a time- and space-dependent electric field. For any bounded convex region $\mathcal{R}\subset \mathbb{…
