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…

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…
