Bridging entanglement dynamics and chaos in semiclassical systems

A Lerose, S Pappalardi - Physical Review A, 2020 - APS
It is widely recognized that entanglement generation and dynamical chaos are intimately
related in semiclassical models via the process of decoherence. In this paper, we propose a …

Entanglement entropy converges to classical entropy around periodic orbits

CT Asplund, D Berenstein - Annals of Physics, 2016 - Elsevier
We consider oscillators evolving subject to a periodic driving force that dynamically
entangles them, and argue that this gives the linearized evolution around periodic orbits in a …

Chaos, decoherence and quantum cosmology

E Calzetta - Classical and quantum gravity, 2012 - iopscience.iop.org
In this topical review we discuss the connections between chaos, decoherence and
quantum cosmology. We understand chaos as classical chaos in systems with a finite …

Entanglement dynamics of spins using a few complex trajectories

MV Scherer, AD Ribeiro - Physical Review A, 2021 - APS
In this paper, we consider two spins initially prepared in a product of coherent states and
study their entanglement dynamics due to a general interacting Hamiltonian. We adopt an …

Entanglement dynamics via semiclassical propagators in systems of two spins

AD Ribeiro, RM Angelo - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
We analyze the dynamical generation of entanglement in systems of two interacting spins
initially prepared in a product of spin coherent states. For arbitrary time-independent …

Enhancing von Neumann entropy by chaos in spin–orbit entanglement

CR Liu, P Yu, XZ Chen, HY Xu, L Huang… - Chinese Physics …, 2019 - iopscience.iop.org
For a quantum system with multiple degrees of freedom or subspaces, loss of coherence in
a certain subspace is intimately related to the enhancement of entanglement between this …

Parametric competition in non-autonomous Hamiltonian systems

LAM Souza, JGP Faria, MC Nemes - Optics Communications, 2014 - Elsevier
In this work we use the formalism of chord functions (ie characteristic functions) to
analytically solve quadratic non-autonomous Hamiltonians coupled to a reservoir composed …
