The contact temperature of arbitrary quantum states
Alain Joye, Marco Merkli
An intuitive scheme to assign a temperature to an arbitrary state of a quantum system is to investigate the heat flow resulting from the coupling to a thermometer. We introduce a s…
Ultrastrongly coupled open systems and fine grained time
Stefano Marcantoni, Marco Merkli
We study the dynamics of a d-level quantum system coupled to a bosonic reservoir when the coupling constant is large. It is known that in the limit of infinite coupling strength, t…
Lectures on Open Quantum Systems
Marco Merkli, Ãngel Neira
These notes are a short introduction to the mathematical theory of open quantum systems. They are meant to serve as an entry point into a broad research area which has applications…
Bosonization of Noise Effects in Nonlocal Quantum Dynamics
Michele Fantechi, Marco Merkli
Quantum systems that interact non-locally with an environment are paradigms for exploring collective phenomena. They naturally emerge in various physical contexts involving long-ra…
Non-Markovianity in collision models with initial intra-environment correlations
Graeme Pleasance, Angel E. Neira, Marco Merkli +1
Collision models (CMs) describe an open system interacting in sequence with elements of an environment, termed ancillas. They have been established as a useful tool for analyzing n…
On the difference between thermalization in open and isolated quantum systems: a case study
Archak Purkayastha, Giacomo Guarnieri, Janet Anders +1
Thermalization of isolated and open quantum systems has been studied extensively. However, being the subject of investigation by different scientific communities and being analysed…
