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…
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…
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…
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…
Correlated Mott insulators in a strong electric field: The effects of phonon renormalization
Tommaso Maria Mazzocchi, Daniel Werner, Paolo Gazzaneo +1
We characterize the response of a Mott insulating system to a static electric field in terms of its conducting and spectral properties. Dissipation is included by a coupling to fer…
Impact ionization processes in a photodriven Mott insulator: influence of phononic dissipation
Paolo Gazzaneo, Tommaso Maria Mazzocchi, Jan Lotze +1
We study a model for photovoltaic energy collection consisting of a Mott insulating layer in presence of acoustic phonons, coupled to two wide-band fermion leads at different chemi…
Correlated Mott insulators in strong electric fields: Role of phonons in heat dissipation
T. M. Mazzocchi, P. Gazzaneo, J. Lotze +1
We study the spectral and transport properties of a Mott insulator driven by a static electric field into a non-equilibrium steady state. For the dissipation, we consider two mecha…
