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…
Strong suppression of near-field radiative heat transfer by superconductivity in NbN
Věra Musilová, Tomáš Králík, Tomáš Fořt +1
Near-field (NF) radiative heat transfer (RHT) over vacuum space between closely spaced bodies can exceed the Planck far-field (FF) values by orders of magnitude. Strong effect of s…
Van Hove Singularities and Excited-State Quantum Phase Transitions in Graphene-like Microwave Billiards
Michal Macek, Barbara Dietz
We discuss solutions of an algebraic model of the hexagonal lattice vibrations, which point out interesting localization properties of the eigenstates at van Hove singularities (vH…
