Resonance Assisted Tunneling in Floquet spin-J systems
J. A. Segura-Landa, Diego A. Wisniacki, Sergio Lerma-Hernández +1
We apply the theory of Resonance Assisted Tunneling (RAT) to a many-body quantum kicked system with a well-defined semiclassical limit. Using a quantum resonant condition, we ident…
Resonant fragility and nonresonant robustness of Floquet eigenstates in kicked spin systems
Jesús A. Segura-Landa, Meenu Kumari, Daniel J. Nader +3
In classical systems, the Kolmogorov-Arnold-Moser (KAM) theorem establishes that resonant tori of integrable Hamiltonians are destroyed by any nonintegrable perturbation, whereas n…
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…
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…
Quantum tunneling and level crossings in the squeeze-driven Kerr oscillator
Miguel A. Prado Reynoso, D. J. Nader, Jorge Chávez-Carlos +6
The quasi-energy spectrum recently measured in experiments with a squeeze-driven superconducting Kerr oscillator showed good agreement with the energy spectrum of its corresponding…
Integrable Model of Topological SO(5) Superfluidity
Will J. Holdhusen, Sergio Lerma-Hernández, Jorge Dukelsky +1
Assisted by general symmetry arguments and a many-body invariant, we introduce a phase of matter that constitutes a topological SO(5) superfluid. Key to this finding is the realiza…
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…
Thermal and Quantum Phase Transitions in Atom-Field Systems: a Microcanonical Analysis
Miguel A. Bastarrachea-Magnani, Sergio Lerma-Hernández, Jorge G. Hirsch
The thermodynamical properties of a generalized Dicke model are calculated and related with the critical properties of its energy spectrum, namely the quantum phase transitions (QP…
