Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

To write an introduction to the dynamics of open quantum systems may seem at first a
complicated, albeit perhaps unnecessary, task. On the one hand, the field is quite broad and …

A procedure that allows us to obtain the dynamics of N independent bodies each locally
interacting with its own reservoir is presented. It relies on the knowledge of single-body …

Here is analyzed the dynamics of two-qubit entanglement, when the two qubits are initially in
a mixed extended Werner-like state and each of them is in a zero temperature non …

Capturing non-Markovian dynamics of open quantum systems is generally a challenging
problem, especially for strongly interacting many-body systems. In this Letter, we combine …

In this paper we investigate the non-Markovian dynamics of a qubit by comparing two
generalized master equations with memory. In the case of a thermal bath, we derive the …

We investigate the dynamics of a giant atom (or atoms) in a waveguide QED scenario,
where the atom couples to the coupled resonator waveguide via two sites. For a single-giant …

We consider a thermofield approach to analyze the evolution of an open quantum system
coupled to an environment at finite temperature. In this approach, the finite-temperature …

We introduce a simple setup corresponding to the matter-wave analogue of impurity atoms
embedded in a photonic crystal and interacting with the radiation field. Atoms in a given …

The dynamics of open quantum systems is formulated in a minimally extended state space
comprising the degrees of freedom of a system of interest and a finite set of non-unitary, pure …
