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…
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…
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…
Quasi-classical Limit of a Spin Coupled to a Reservoir
Michele Correggi, Marco Falconi, Michele Fantechi +1
A spin (qubit) is in contact with a bosonic reservoir. The state of the reservoir contains a parameter {\varepsilon} interpolating between quantum and classical reservoir features.…
Rigorous results on approach to thermal equilibrium, entanglement, and nonclassicality of an optical quantum field mode scattering from the elements of a non-equilibrium quantum reservoir
Stephan De Bievre, Marco Merkli, Paul E. Parris
Rigorous derivations of the approach of individual elements of large isolated systems to a state of thermal equilibrium, starting from arbitrary initial states, are exceedingly rar…
Entropy and entanglement in a bipartite quasi-Hermitian system and its Hermitian counterparts
Abed Alsalam Abu Moise, Graham Cox, Marco Merkli
We consider a quantum oscillator coupled to a bath of other oscillators. The total system evolves with a quasi-Hermitian Hamiltonian. Associated to it is a family of Hermitian…
