Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC-BCS Crossover. [PDF]
Adv Sci (Weinh)This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Neue Computermodelle erklären Sternexplosionen
Physik in unserer Zeit, Volume 54, Issue 6, Page 274-282, November 2023., 2023 Massereiche Sterne können am Ende ihres Lebens als Supernova explodieren, während ihr Kern zu einem Neutronenstern oder Schwarzen Loch kollabiert. Stetig verbesserte Computermodelle und die Entdeckung seltener Arten von Explosionen eröffnen immer tiefere Einblicke in die komplexen Phänomene beim Sternentod.

Eichtheorien im Quantensimulator
Physik in unserer Zeit, Volume 54, Issue 5, Page 246-253, September 2023., 2023 Großskalige Quantensimulatoren versprechen die kontrollierte Untersuchung komplexer Fragestellungen auf verschiedenen Gebieten der Physik. Das kontrollierte Zusammenspiel von quantenmechanischen Bausteinen könnte ein detaillierteres Verständnis von Eichtheorien und somit der Grundkräfte der Natur ermöglichen.

Günter Kelbg, the Kelbg potential and its impact on quantum plasma theory
Contributions to Plasma Physics, Volume 63, Issue 3-4, May 2023., 2023 Abstract Günter Kelbg did remarkable early work in the field of quantum statistical physics, in particular for dense quantum plasmas. In 2022 we celebrated his 100th birthday. On this occasion, we give a brief overview of his main scientific achievements in the field of quantum plasmas, complemented by some biographical background of his research and ...

Journal of Geophysical Research: Planets, Volume 128, Issue 4, April 2023., 2023 Abstract The Radiation Assessment Detector (RAD) on board the Mars Science Laboratory's Curiosity rover has been monitoring the surface radiation environment on Mars for just over 10 years. It has been found by Wimmer‐Schweingruber et al. (2015, https://doi.org/10.1002/2015gl066664) that within the narrow view cone of RAD, the directionality of the ...

European Journal of Physics, 2003 We study the evolution of matter produced after the collision of two heavy nuclei at high energy. The matter produced may pass from the hadron phase into a new state of matter called quark–gluon plasma (QGP). The aim of this paper is to discuss how a new state of matter can be observed.

DECONFINEMENT AND QUARK–GLUON PLASMA [PDF]
International Journal of Modern Physics E, 2009 The theory of confinement and deconfinement is discussed as based on the properties of the QCD vacuum. The latter are described by field correlators of color-electric and color-magnetic fields in the vacuum, which can be calculated analytically and on the lattice.

Particle Ratios in a Multicomponent Nonideal Hadron Resonance Gas
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We have considered formation of a multicomponent nonideal hot and dense gas of hadronic resonances in the ultrarelativistic heavy ion collisions. In the statistical thermal model approach, the equation of state (EoS) of the noninteracting ideal hadron resonance gas (IHRG) does not incorporate either the attractive part or the short‐range repulsive part

Anisotropic Behavior of S‐Wave and P‐Wave States of Heavy Quarkonia at Finite Magnetic Field
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We studied the effect of momentum space anisotropy on heavy quarkonium states using an extended magnetized effective fugacity quasiparticle model (EQPM). Both the real and imaginary part of the potential has been modified through the dielectric function by including the anisotropic parameter ξ.

Relaxation time for quark spin and thermal vorticity alignment in heavy-ion collisions
Physics Letters B, 2020 We compute the relaxation time for quark/antiquark spin and thermal vorticity alignment in a quark-gluon plasma at finite temperature and quark chemical potential.
