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…
Steady-state spectral kissing and dissipative phase transitions
Devesh Karthik, Jorge Chávez-Carlos, Edson M. Signor +3
Spectral kissing, recently realized in a Kerr parametric oscillator (KPO), refers to the merging of pairs of energy levels and arises as a manifestation of an excited-state quantum…
Instability-Enhanced Quantum Sensing with Tunable Multibody Interactions
Bidhi Vijaywargia, Jorge Chávez-Carlos, Francisco Pérez-Bernal +1
Dynamical instabilities can amplify small perturbations into measurable signals, offering a route to quantum-enhanced sensing. This mechanism was experimentally demonstrated in a c…
Impact of chaos on the excited-state quantum phase transition of the Kerr parametric oscillator
Ignacio GarcÃa-Mata, Miguel A. Prado Reynoso, Rodrigo G. Cortiñas +4
The driven Kerr parametric oscillator, of interest to fundamental physics and quantum technologies, exhibits an excited state quantum phase transition (ESQPT) originating in an uns…
A Roadmap for Simulating Chemical Dynamics on a Parametrically Driven Bosonic Quantum Device
Delmar G. A. Cabral, Pouya Khazaei, Brandon C. Allen +8
Chemical reactions are commonly described by the reactive flux transferring population from reactants to products across a double-well free energy barrier. Dynamics often involves…
Quantum sensing in Kerr parametric oscillators
Jorge Chávez-Carlos, Daniela Garrido-RamÃrez, A. J. Vega Carmona +5
Quantum metrology and quantum sensing aim to use quantum properties to enhance measurement precision beyond what could be classically achieved. Here, we demonstrate how the analysi…
