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…

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…
