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…

Characterizing the excited-state quantum phase transition via the dynamical and statistical properties of the diagonal entropy
Qian Wang, Francisco Pérez-Bernal
Using the diagonal entropy, we analyze the dynamical signatures of the Lipkin-Meshkov-Glick (LMG) model excited-state quantum phase transition (ESQPT). We first show that the time…
