How rare are Markovian quantum dynamics?
Charlotte Bäcker, Nick Maryshchak, Walter T. Strunz
A profound understanding of decoherence and dissipation in quantum dynamics is crucial for the realistic modeling of the evolution of quantum systems. In open quantum dynamics one…
Benchmarking Floquet Master Equations for Periodically Driven Open Quantum Systems
Konrad Mickiewicz, Valentin Link, Walter T. Strunz
The dynamics of open quantum systems is commonly described by quantum master equations derived under the assumption of weak system-bath coupling and a separation of timescales betw…
One-to-one correspondence between Hierarchical Equations of Motion and Pseudomodes for Open Quantum System Dynamics
Kai Müller, Walter T. Strunz
We unite two of the most widely used approaches for strongly damped, non-Markovian open quantum dynamics, the Hierarchical Equations of Motion (HEOM) and the pseudomode method by p…
Quantum memory precludes mixed-unitary dynamics
Charlotte Bäcker, Konstantin Beyer, Walter T. Strunz
Unital quantum channels, defined by their property of leaving the maximally mixed state invariant, form an important class of quantum operations. A distinguished subset of these ch…
Uniform process tensor approach for the calculation of multi-time correlation functions of non-Markovian open systems
Matteo Garbellini, Konrad Mickiewicz, Valentin Link +2
The process tensor framework to open quantum systems provides the most general description of multi-time correlations in non-Markovian quantum dynamics. A compressed representation…
Non-Markovian dynamics of the giant atom beyond the rotating-wave approximation
Mei Yu, Walter T. Strunz, Stefan Nimmrichter
We study the non-Markovian dynamics of a giant artificial atom coupled to a one-dimensional acoustic waveguide beyond the rotating-wave and weak-coupling approximations. By combini…
