Mixed-configuration approximation for multiorbital systems out of equilibrium
Tommaso Maria Mazzocchi, Daniel Werner, Markus Aichhorn +1
We propose a mixed-configuration approximation based on single-band impurity solvers to efficiently study nonequilibrium multiorbital systems at moderate computational cost. In thi…
Functional interpolation expansion for nonequilibrium correlated impurities
Daniel Werner, Enrico Arrigoni
We present a functional interpolation approach within the auxiliary master equation framework to efficiently and accurately solve correlated impurity problems in nonequilibrium dyn…
Photodriven Mott insulating heterostructures: A steady-state study of impact ionization processes
Paolo Gazzaneo, Daniel Werner, Tommaso Maria Mazzocchi +1
We investigate the photocurrent and spectral features in a simplified model of a Mott photovoltaic system consisting of a multilayered insulating heterostructure. The central corre…
Numerically exact simulation of photo-doped Mott insulators
Fabian Künzel, André Erpenbeck, Daniel Werner +4
A description of long-lived photo-doped states in Mott insulators is challenging, as it needs to address exponentially separated timescales. We demonstrate how properties of such s…
Auxiliary master equation approach to the Anderson-Holstein impurity problem out of equilibrium
D. Werner, R. Žitko, E. Arrigoni
We introduce a method based on auxiliary master equation for solving the problem of an impurity with local electron-electron and electron-phonon interaction embedded between two co…
Impact of disorder and phonons on the Hubbard bands of Mott insulators in strong electric fields
Tommaso Maria Mazzocchi, Daniel Werner, Enrico Arrigoni
We characterize the current-carrying non-equilibrium steady-state (NESS) in a single-band Hubbard model confronted with a static electric field in the presence of quenched disorder…
Configuration interaction based nonequilibrium steady state impurity solver
D. Werner, J. Lotze, E. Arrigoni
We present a solver for correlated impurity problems out of equilibrium based on a combination of the so-called auxiliary master equation approach (AMEA) and the configuration inte…
