Semiclassical limit of entropies and free energies
Zied Ammari, Michele Correggi, Marco Falconi +1
Entropy and free energy are central concepts in both statistical physics and information theory, with quantum and classical facets. In mathematics these concepts appear quite often…

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.…

Quantum Point Charges Interacting with Quasi-classical Electromagnetic Fields
S. Breteaux, M. Correggi, M. Falconi +1
We study effective models describing systems of quantum particles interacting with quantized (electromagnetic) fields in the quasi-classical regime, i.e., when the field's state sh…
