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…
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…
Impact of chaos on the excited-state quantum phase transition of the Kerr parametric oscillator
Ignacio García-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…
Quantum sensing in Kerr parametric oscillators
Jorge Chávez-Carlos, Daniela Garrido-Ramírez, 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…
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…
