Optimized auxiliary representation of a non-Markovian environment by a Lindblad equation
Antonius Dorda, Max E. Sorantin, Wolfgang von der Linden +1
We present a general scheme to map correlated nonequilibrium quantum impurity problems onto an auxiliary open quantum system of small size. The infinite fermionic reservoirs of the…
Thermoelectric response of a correlated impurity in the nonequilibrium Kondo regime
Antonius Dorda, Martin Ganahl, Sabine Andergassen +2
We study nonequilibrium thermoelectric transport properties of a correlated impurity connected to two leads for temperatures below the Kondo scale. At finite bias, for which a curr…
Resonance Effects in Correlated Multilayer Heterostructures
Irakli Titvinidze, Antonius Dorda, Wolfgang von der Linden +1
We study the occurrence of negative differential conductance induced by resonance effects in a model for a multilayer heterostructure. In particular, we consider a system consistin…
Non-equilibrium variational cluster perturbation theory: quench dynamics of the quantum Ising model
Mohammad Zhian Asadzadeh, Michele Fabrizio, Enrico Arrigoni
We introduce a variational implementation of cluster perturbation theory (CPT) to address the dynamics of spin systems driven out of equilibrium. We benchmark the method with the q…
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…
