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…
Degeneracy in excited-state quantum phase transitions of two-level bosonic models and its influence on system dynamics
J. Khalouf-Rivera, Qian Wang, Lea F. Santos +3
Excited-state quantum phase transitions (ESQPTs) strongly influence the spectral properties of collective many-body quantum systems, changing degeneracy patterns in different quant…
