Dynamics of a strongly coupled quantum heat engine -- computing bath observables from the hierarchy of pure states
Valentin Boettcher, Richard Hartmann, Konstantin Beyer +1
We present a fully quantum dynamical treatment of a quantum heat engine and its baths based on the Hierarchy of Pure States (HOPS), an exact and general method for open quantum sys…
Environmentally Induced Entanglement -- Anomalous Behavior in the Adiabatic Regime
Richard Hartmann, Walter T. Strunz
Considering two non-interacting qubits in the context of open quantum systems, it is well known that their common environment may act as an entangling agent. In a perturbative regi…
Accuracy Assessment of Perturbative Master Equations -- Embracing Non-Positivity
Richard Hartmann, Walter T. Strunz
The reduced dynamics of an open quantum system obtained from an underlying microscopic Hamiltonian can in general only approximately be described by a time local master equation. T…
Exact open quantum system dynamics using the Hierarchy of Pure States (HOPS)
Richard Hartmann, Walter T. Strunz
We show that the general and numerically exact Hierarchy of Pure States method (HOPS) is very well applicable to calculate the reduced dynamics of an open quantum system. In partic…
