Nonequilibrium Steady-State Transport in Quantum Impurity Models: a Thermofield and Quantum Quench Approach using Matrix Product States
Frauke Schwarz, Ireneusz Weymann, Jan von Delft +1
The numerical renormalization group (NRG) is tailored to describe interacting impurity models in equilibrium, but faces limitations for steady-state nonequilibrium, arising, e.g.,…
Nonequilibrium Kondo effect in a magnetic field: Auxiliary master equation approach
Delia M. Fugger, Antonius Dorda, Frauke Schwarz +2
We study the single-impurity Anderson model out of equilibrium under the influence of a bias voltage and a magnetic field . We investigate the interplay between the shift ($…
Open Wilson chains for quantum impurity models: Keeping track of all bath modes
Benedikt Bruognolo, Nils-Oliver Linden, Frauke Schwarz +6
When constructing a Wilson chain to represent a quantum impurity model, the effects of truncated bath modes are neglected. We show that their influence can be kept track of systema…
Lindblad-Driven Discretized Leads for Non-Equilibrium Steady-State Transport in Quantum Impurity Models: Recovering the Continuum Limit
Frauke Schwarz, Moshe Goldstein, Antonius Dorda +3
The description of interacting quantum impurity models in steady-state nonequilibrium is an open challenge for computational many-particle methods: the numerical requirement of usi…
