Quantum Entropies and Decoherence for the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
I study the scaling behavior in the physical parameters of dynamical entropies, classical and quantum, in a specifically devised model of collision-induced decoherence in a chaotic…
Behavior of correlation functions in the dynamics of the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
The multi-particle Arnol'd cat is a generalization of the Hamiltonian system, both classical and quantum, whose period evolution operator is the renown map that bears its name. It…
A Scale-Dependent Distance Functional between Past Light Cones in Cosmology
Mauro Carfora, Francesca Familiari
We discuss a rigorous procedure for quantifying the difference between our past lightcone and the past lightcone of the fiducial Friedmann-Lemaitre-Robertson-Walker spacetime model…
Ricci curvature and quantum geometry
Mauro Carfora, Francesca Familiari
We describe a few elementary aspects of the circle of ideas associated with a quantum field theory (QFT) approach to Riemannian Geometry, a theme related to how Riemannian structur…
Regular patterns in the information flow of local dephasing channels
Filippo Giraldi
Consider local dephasing processes of a qubit that interacts with a structured reservoir of frequency modes or a thermal bath, with Ohmic-like spectral density (SD). It is known th…
