Auxiliary quantum master equation for nonequilibrium dual-fermion approach

ORAL

Abstract

We introduce auxiliary quantum master equation - dual fermion approach (AQME-DF) and argue that it presents a convenient way to describe steady states of non-equilibrium correlated impurity systems. The combined scheme yields an expansion around a reference system much closer to the true system than in the previous considerations. This scheme also avoids long time propagation and hence is numerically cheaper. Results for Anderson impurity model (AIM) are presented as a benchmark.
