Quantum dynamical maps provide suitable mathematical representation of quantum
evolutions. When representing quantum states by density operators, the evident …

We analyze and compare different measures for the degree of non-Markovianity in the
dynamics of open quantum systems. These measures are based on the distinguishability of …

In the dynamics of open quantum systems, the backflow of information to the reduced system
under study has been suggested as the actual physical mechanism inducing memory and …

Recently, there has been an upsurge of interest in quantum thermodynamic devices, notably
quantum batteries. Quantum batteries serve as energy storage devices governed by the …

The dynamics of open quantum systems is often solved by stochastic unravelings where the
average over the state-vector realizations reproduces the density matrix evolution. We focus …

Master equations are a useful tool to describe the evolution of open quantum systems. In
order to characterize the mathematical features and the physical origin of the dynamics, it is …

We examine the emergence of dynamical memory effects in quantum processes having
indefinite time direction and causal order. In particular, we focus on the class of phase …

A dynamical symmetry is employed to determine the structure of the quantum non-
Markovian time-local master equation. Such a structure is composed from two components …

The quantum speed of evolution for the phase covariant map is investigated. This involves
absorption, emission, and dephasing processes. The maps under various combinations of …

Quantum collision models have proved to be useful for a clear and concise description of
many physical phenomena in the field of open quantum systems: thermalization …
