On spatial decoherence in many-body systems
Stefano Marcantoni, Marco Merkli
We study the dynamics of a many-body quantum system strongly interacting with a bosonic reservoir. The coupling is given by a potential operator for the system and it is linear in…
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…
Fluctuation Relations associated to an arbitrary bijection in path space
Raphael Chetrite, Stefano Marcantoni
We introduce a framework to identify Fluctuation Relations for vector-valued observables in physical systems evolving through a stochastic dynamics. These relations arise from the…
Ultrastrong coupling, nonselective measurement and quantum Zeno dynamics
Stefano Marcantoni, Marco Merkli
We study the dynamics of an open quantum system linearly coupled to a bosonic reservoir. We show that, in the ultrastrong coupling limit, the system undergoes a nonselective measur…
Dynamics of mean-field Fermi systems with nonzero pairing
Stefano Marcantoni, Marcello Porta, Julien Sabin
We study the dynamics of many-body Fermi systems, for a class of initial data which are close to quasi-free states exhibiting a nonvanishing pairing matrix. We focus on the mean-fi…
Stochastic entropy production: Fluctuation relation and irreversibility mitigation in non-unital quantum dynamics
Eliana Fiorelli, Stefano Gherardini, Stefano Marcantoni
In this work, we study the stochastic entropy production in open quantum systems whose time evolution is described by a class of non-unital quantum maps. In particular, as in [Phys…
