Probing excited-state quantum phase transitions with trapped cold ions
Marek Kuchař, Michal Macek
We propose concrete protocols to realize quantum criticality due to excited-state quantum phase transitions (ESQPTs) experimentally in presumably the simplest and most resilient sy…
Effect of boundary conditions in turbulent thermal convection
P. Urban, T. Králík, M. Macek +2
We report an experimental study aiming to clarify the role of boundary conditions (BC) in high Rayleigh number turbulent thermal convection of…
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…
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…
Excited-State Quantum Phase Transitions in Bosonic Lattice Systems
Michal Macek
Concentrating on bosonic lattice systems, we ask whether and how Excited State Quantum Phase Transition (ESQPT) singularities occur in condensed matter systems with ground state QP…
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…
