Chaos in a deformed Dicke model
Ángel L. Corps, Rafael A. Molina, Armando Relaño
The critical behavior in an important class of excited state quantum phase transitions is signaled by the presence of a new constant of motion only at one side of the critical ener…

Constant of motion identifying excited-state quantum phases
Ángel L. Corps, Armando Relaño
We propose that a broad class of excited-state quantum phase transitions (ESQPTs) gives rise to two different excited-state quantum phases. These phases are identified by means of…
