We present a detailed analysis of the connection between chaos and the onset of thermalization in the spin-boson Dicke model. This system has a well-defined classical limit with two degrees of freedom, and it presents both regular and chaotic regions

Quantum scarring in a spin-boson system: fundamental families of periodic orbits

Autor: Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A Bastarrachea-Magnani, Sergio Lerma-Hernández, Lea F Santos, Jorge G Hirsch

Publikováno v: New Journal of Physics, Vol 23, Iss 3, p 033045 (2021)

As the name indicates, a periodic orbit is a solution for a dynamical system that repeats itself in time. In the regular regime, periodic orbits are stable, while in the chaotic regime, they become unstable. The presence of unstable periodic orbits i

In a classically chaotic system that is ergodic, any trajectory will be arbitrarily close to any point of the available phase space after a long time, filling it uniformly. Using Born's rules to connect quantum states with probabilities, one might th

Identification of quantum scars via phase-space localization measures

Publikováno v: Quantum, Vol 6, p 644 (2022)

There is no unique way to quantify the degree of delocalization of quantum states in unbounded continuous spaces. In this work, we explore a recently introduced localization measure that quantifies the portion of the classical phase space occupied by
