Fit-error corrected auxiliary master equation approach for low-temperature nonequilibrium dynamical mean-field theory
Sebastian Alois Fuchs, Enrico Arrigoni, Tommaso Maria Mazzocchi
The auxiliary master equation approach (AMEA) is a nonperturbative impurity solver for steady-state nonequilibrium dynamical mean-field theory (DMFT). It replaces the physical hybr…
Extension of the iterated perturbation theory at arbitrary fillings to nonequilibrium steady states
Tommaso Maria Mazzocchi, Enrico Arrigoni
We extend the Kajueter-Kotliar [Phys. Rev. Lett. 77, 131 (1996)] iterated perturbation theory (KK-IPT) away from half filling to nonequilibrium steady states. We benchmark the resu…
Steady-state study of the nonequilibrium properties of SrVO
Tommaso Maria Mazzocchi, Markus Aichhorn, Enrico Arrigoni
We present the mixed-configuration approximation (MCA) based on the auxiliary master equation approach impurity solver to study multiorbital correlated systems under equilibrium an…
Nonequilibrium transport through an interacting monitored quantum dot
Daniel Werner, Matthieu Vanhoecke, Marco Schirò +1
We study the interplay between strong correlations and Markovian dephasing, resulting from monitoring the charge or spin degrees of freedom of a quantum dot described by a dissipat…
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…
Phonon effects, impact ionization and power conversion in Mott photovoltaic systems
Paolo Gazzaneo, Enrico Arrigoni
We analyze the effect of acoustic phonons on the photocurrent and the spectral characteristics of a simplified photovoltaic setup made of Mott insulating layers between two metalli…
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…
Iterated Perturbation Theory for Mott Insulators in a Static Electric Field with Optical Phonons
Tommaso Maria Mazzocchi, Enrico Arrigoni
This manuscript aims to compare the so-called iterated perturbation theory (IPT) and auxiliary master equation approach (AMEA) impurity solvers for a Mott insulating system driven…
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…

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…
