Classical and Quantum Properties of the Spin-Boson Dicke Model: Chaos, Localization, and Scarring
David Villaseñor, Saúl Pilatowsky-Cameo, Jorge Chávez-Carlos +4
This review article describes major developments associated with the Dicke model, from its introduction in the 1950s to explain the transition from a normal to a superradiant phase…
Exceptional points in dissipative coupling polaron-polaritons
A. J. Vega-Carmona, D. A. Mendoza, A. Camacho-Guardian +1
Understanding how strong correlations and dissipation combine to shape collective quantum excitations is a central challenge in many-body physics. We investigate the effect of diss…
Non-Markovian entropy production fluctuation theorem driven by a time-dependent electric field
K. S. RodrÃguez-Vigil, M. A. Bastarrachea-Magnani, J. I. Jiménez-Aquino
Fluctuation theorems are key to understanding both fundamental and applied aspects of non-equilibrium thermodynamics of small systems. We study the non-Markovian entropy production…
Chaos and Regularity in an Anisotropic Soft Squircle Billiard
A. González-Andrade, H. N. Núñez-Yépez, M. A. Bastarrachea-Magnani
A hard-wall billiard is a mathematical model describing the confinement of a free particle that collides specularly and instantaneously with boundaries and discontinuities. Soft bi…
Effective Mass in Dissipative Coupled Polaritons
Diego A. Mendoza, Areli J. Vega-Carmona, Arturo Camacho-Guardian +1
Dissipative coupling refers to the effect where two systems interact with each other mediated by dissipation channels. Recent advances in controlling light-matter systems have open…
Quantum multifractality as a probe of phase space in the Dicke model
Miguel A. Bastarrachea-Magnani, David Villaseñor, Jorge Chávez-Carlos +3
We study the multifractal behavior of coherent states projected in the energy eigenbasis of the spin-boson Dicke Hamiltonian, a paradigmatic model describing the collective interac…
