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…
