Abstract
We present a method to compute electronic steady state properties of strongly correlated quantum systems out of equilibrium within
dynamical mean-field theory (DMFT). The DMFT solver is based on the exact solution of an auxiliary system consisting of a small
number of bath sites coupled to the interacting impurity and to two Markovian reservoirs. The steady state Green's function of the
auxiliary system is solved by exact diagonalisation of the corresponding many-body Lindblad equation. The approach can be regarded
as the non-equilibrium extension of the exact-diagonalization based DMFT.
