Disorder and interactions in systems out of equilibrium : The exact independent-particle picture from density functional theory
(2018) In Physical Review B 97(12).- Abstract
Density functional theory (DFT) exploits an independent-particle-system construction to replicate the densities and current of an interacting system. This construction is used here to access the exact effective potential and bias of nonequilibrium systems with disorder and interactions. Our results show that interactions smoothen the effective disorder landscape but do not necessarily increase the current due to the competition of disorder screening and effective bias. This puts forward DFT as a diagnostic tool to understand disorder screening in a wide class of interacting disordered systems.
