Degeneracy beyond the parity-symmetry protection in the Lipkin-Meshkov-Glick model
Jamil Khalouf-Rivera, Miguel Carvajal, Francisco Pérez-Bernal
Degeneracy patterns in quantum mechanics stem from the system symmetries. In particular, the broken-symmetry phase in the well-known Lipkin-Meshkov-Glick (LMG) model is composed of…
Degeneracy beyond the parity-symmetry protection in one-dimensional spinless models: The parity-violating Kerr parametric oscillator
Jamil Khalouf-Rivera, Miguel Carvajal, Francisco Pérez-Bernal
One-dimensional quantum systems that undergo spontaneous symmetry-breaking, having a symmetric (non-degenerate) and a broken-symmetry (doubly-degenerate) phase, have been intensely…
Phase transitions, symmetries, and tunneling in Kerr parametric oscillators
Miguel A. Prado Reynoso, Edson M. Signor, Jamil Khalouf-Rivera +3
Quantum Kerr parametric oscillators (KPOs) are systems out of equilibrium with a wide range of applications in quantum computing, quantum sensing, and fundamental research. They ha…
Quantum Phase Transitions in periodically quenched systems
Á. Sáiz, J. Khalouf-Rivera, J. M. Arias +2
Quantum phase transitions encompass a variety of phenomena that occur in quantum systems exhibiting several possible symmetries. Traditionally, these transitions are explored by co…
Excited-State Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Dynamical Aspects
Jamil Khalouf-Rivera, Juan Gamito, Francisco Pérez-Bernal +2
The standard Lipkin-Meshkov-Glick (LMG) model undergoes a second-order ground-state quantum phase transition (QPT) and an excited-state quantum phase transition (ESQPT). The inclus…
Excited-State Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model I: Static Aspects
Juan Gamito, Jamil Khalouf-Rivera, J. Miguel Arias +2
The basic Lipkin-Meshkov-Glick model displays a second order ground state quantum phase transition and an excited state quantum phase transition (ESQPT). The inclusion of an anharm…
Anharmonicity-induced excited-state quantum phase transition in the symmetric phase of the two-dimensional limit of the vibron model
Jamil Khalouf-Rivera, Francisco Pérez-Bernal, Miguel Carvajal
In most cases, excited state quantum phase transitions can be associated with the existence of critical points (local extrema or saddle points) in a system's classical limit energy…
Quantum fidelity susceptibility in excited state quantum phase transitions: application to the bending spectra of nonrigid molecules
J. Khalouf-Rivera, M. Carvajal, F. Pérez-Bernal
We characterize excited state quantum phase transitions in the two dimensional limit of the vibron model with the quantum fidelity susceptibility, comparing the obtained results wi…
