Charging a quantum battery in a non-Markovian environment: a collisional model approach
Daniele Morrone, Matteo A. C. Rossi, Andrea Smirne +1
We study the effect of non-Markovianity in the charging process of an open-system quantum battery. We employ a collisional model framework, where the environment is described by a…
On the use of total state decompositions for the study of reduced dynamics
Andrea Smirne, Nina Megier, Bassano Vacchini
The description of the dynamics of an open quantum system in the presence of initial correlations with the environment needs different mathematical tools than the standard approach…
Non-perturbative treatment of open-system multi-time expectation values in Gaussian bosonic environments
A. Smirne, D. Tamascelli, J. Lim +2
We determine the conditions for the equivalence between the multi-time expectation values of a general finite-dimensional open quantum system when interacting with, respectively, a…
Fingerprint and universal Markovian closure of structured bosonic environments
Alexander Nüßeler, Dario Tamascelli, Andrea Smirne +3
We exploit the properties of chain mapping transformations of bosonic environments to identify a finite collection of modes able to capture the characteristic features, or fingerpr…
Correlations, information backflow, and objectivity in a class of pure dephasing models
Nina Megier, Andrea Smirne, Steve Campbell +1
We critically examine the role that correlations established between a system and fragments of its environment play in characterising the ensuing dynamics. We employ a class of dep…
Holevo skew divergence for the characterization of information backflow
Andrea Smirne, Nina Megier, Bassano Vacchini
The interpretation of non-Markovian effects as due to the information exchange between an open quantum system and its environment has been recently formulated in terms of properly…
