Query: Nonequilibrium DMFT+CPA for Correlated Disordered Systems   We present a solution for the nonequilibrium dynamics of an interacting
disordered system. The approach adapts the combination of the equilibrium
dynamical mean field theory (DMFT) and the equilibrium coherent potential
approximation (CPA) methods to the nonequilibrium many-body formalism, using
the Kadanoff-Baym-Keldysh complex time contour, for the dynamics of interacting
disordered systems away from equilibrium. We use our time domain solution to
obtain the equilibrium density of states of the disordered interacting system
described by the Anderson-Hubbard model, bypassing the necessity for the
cumbersome analytical continuation process. We further apply the nonequilibrium
solution to the interaction quench problem for an isolated disordered system.
Here, the interaction is abruptly changed from zero (non-interacting system) to
another constant (finite) value at which it is subsequently kept. We observe
via the time-dependence of the potential, kinetic, and total energies, the
effect of disorder on the relaxation of the system as a function of final
interaction strength. The real-time approach has the potential to shed new
light on the fundamental role of disorder in the nonequilibrium dynamics of
interacting quantum systems.
