Visualizing gravitational Bessel waves
Aleš Paták, Martin Zouhar, Tomáš Řiháček +3
We explicitly derive a~vortex inspired solution for the metric perturbation within the linearized Einsteins general theory of relativity in arbitrary dimensions . We focus…
Investigating the use of the hydrogen cyanide (HCN) as an absorption media for laser spectroscopy
Martin Hosek, Simon Rerucha, Lenka Pravdova +4
The laser spectroscopy is a fundamental approach for the realisation of traceable optical frequency standards. In the m wavelength band, widely used in telecommunications,…
Laser source for dimensional metrology: investigation of an iodine stabilized system based on narrow linewidth 633 nm DBR diode
Simon Rerucha, Andrew Yacoot, Tuan M Pham +4
We demonstrated that an iodine stabilized Distributed Bragg Reflector (DBR) diode based laser system lasing at a wavelength in close proximity to nm could be used as an a…
Linearized and Compensated Interferometric System for High-Velocity Traceable Length Calibration on a Metre Scale
Simon Rerucha, Bretislav Mikel, Zdenek Matej +6
We report on a traceable calibration system for a 3500mm-long console that carries a measurement system for inspecting the diameter of a circular reactor chassis. The system uses t…
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…
A room-temperature ion trapping apparatus with hydrogen partial pressure below mBar
P. Obšil, A. Lešundák, T. Pham +5
The lifetime of trapped ion ensembles corresponds to a crucial parameter determining the potential scalability of their prospective applications and is often limited by the achieva…
Measurement of the cross section for hard exclusive leptoproduction
M. G. Alexeev, G. D. Alexeev, A. Amoroso +199
We report on a measurement of hard exclusive muoproduction on the proton by COMPASS using 160 GeV/ polarised and beams of the CERN SPS impinging on a liquid hy…
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…
