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…

Universal spectral correlations in open Floquet systems with localized leaks
Edson M. Signor, Miguel A. Prado Reynoso, Bidhi Vijaywargia +2
We show that introducing a localized leak in Floquet systems with time-reversal symmetry leads to universal spectral correlations governed by the non-Hermitian symmetry class $\mat…

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…
