Memory effects displayed in the evolution of continuous variable system
arXiv:2204.05950 · doi:10.1016/j.physleta.2023.128894
Abstract
We analyze non-Markovian memory effects displayed by the quantum Brownian motion modelled as quantum harmonic oscillators coupled to a bath consisting of harmonic oscillators. We study the time evolution of fidelity, Petz-Rényi relative entropy and quantum entanglement for a family of 1-, 2- and 3-mode Gaussian states.
