Quantum scarring in a spin-boson system: fundamental families of periodic orbits
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
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 re…
Ubiquitous quantum scarring does not prevent ergodicity
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
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 B…
Quantum Phase Transition and Berry Phase in an Extended Dicke Model
C. A. Estrada Guerra, J. Mahecha-Gómez, J. G. Hirsch
We investigate quantum phase transitions, quantum criticality, and Berry phase for the ground state of an ensemble of non-interacting two-level atoms embedded in a non-linear optic…
Quantum chaos in a system with high degree of symmetries
Javier de la Cruz, Sergio Lerma-Hernandez, Jorge G. Hirsch
We study dynamical signatures of quantum chaos in one of the most relevant models in many-body quantum mechanics, the Bose-Hubbard model, whose high degree of symmetries yields a l…
Experimental realization of the classical Dicke model
Mario A. Quiroz-Juárez, Jorge Chávez-Carlos, José L. Aragón +2
We report the experimental implementation of the Dicke model in the semiclassical approximation, which describes a large number of two-level atoms interacting with a single-mode el…
Quantum vs classical dynamics in a spin-boson system: manifestations of spectral correlations and scarring
D Villasenor, S Pilatowsky-Cameo, M A Bastarrachea-Magnani +3
We compare the entire classical and quantum evolutions of the Dicke model in its regular and chaotic domains. This is a paradigmatic interacting spin-boson model of great experimen…
