Excited-state quantum phase transitions
Pavel Cejnar, Pavel Stránský, Michal Macek +1
We review the effects of excited-state quantum phase transitions (ESQPTs) in interacting many-body systems with finite numbers of collective degrees of freedom. We classify typical…

Quasiclassical approach to quantum quench dynamics in the presence of an excited-state quantum phase transition
Michal Kloc, Daniel Šimsa, Filip Hanák +3
The dynamics of a quantum system following a sudden, highly non-adiabatic change of its control parameter (quantum quench) is studied with quasiclassical techniques. Recent works h…
