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…
Mixed eigenstates in spin-boson systems with one-photon and two-photon interactions
David Villaseñor, Marko Robnik
Spin-boson systems have attracted increasing attention as accessible experimental platforms and for their potential applications in designing quantum technologies. One characterist…
Superradiant Phase is a Finite Size Effect in Two-photon Processes
Fabrizio RamÃrez, David Villaseñor, Nahum Vázquez +1
Two-photon light-matter interactions exhibit distinctive features such as spectral collapse. The two-photon Dicke model has been reported to exhibit a superradiant phase which coul…
Loss of integrability in a system with two-photon interactions
Fabrizio RamÃrez, David Villaseñor, Viani S. Morales-Guzmán +2
Light-matter systems that exhibit two-photon interactions have emerged as powerful platforms for exploring quantum applications. In this work, we focus on the two-photon Dicke mode…
Correspondence principle, dissipation, and Ginibre ensemble
David Villaseñor, Hua Yan, Matic Orel +1
The correspondence between quantum and classical behavior has been essential since the advent of quantum mechanics. This principle serves as a cornerstone for understanding quantum…
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…
