Superradiance in finite quantum systems randomly coupled to continuum
Pavel Stránský, Pavel Cejnar
We study the effect of superradiance in open quantum systems, i.e., the separation of short- and long-living eigenstates when a certain subspace of states in the Hilbert space acqu…

Excited-state quantum phase transitions in systems with two degrees of freedom: III. Interacting boson systems
Michal Macek, Pavel Stránský, Amiram Leviatan +1
The series of articles [Ann. Phys. 345, 73 (2014) and 356, 57 (2015)] devoted to excited-state quantum phase transitions (ESQPTs) in systems with degrees of freedom is contin…

Order, Chaos and (Quasi-) Dynamical Symmetries across 1st-order Quantum Phase Transitions in Nuclei
Michal Macek, Pavel Cejnar, Pavel Stránský +2
First order quantum phase transition (QPT) between spherical and axially deformed nuclei shows coexisting, but well-separated regions of regular and chaotic dynamics. We employ a H…
