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 ...

The Zenith‐Angle Dependence of the Downward Radiation Dose Rate on the Martian Surface: Modeling Versus MSL/RAD Measurement

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 ...

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

Universal quark to gluon ratio in medium-induced parton cascade

Journal of High Energy Physics, 2018
We investigate the radiative break-up of a highly energetic quark or gluon in a high-temperature QCD plasma. Within an inertial range of momenta T ≪ ω ≪ E, where E denotes the energy of the original hard parton (jet) and T the temperature of the medium ...

Soft Gluon Radiation off Heavy Quarks beyond Eikonal Approximation

Advances in High Energy Physics, 2016
We calculate the soft gluon radiation spectrum off heavy quarks (HQs) interacting with light quarks (LQs) beyond small angle scattering (eikonality) approximation and thus generalize the dead-cone formula of heavy quarks extensively used in the ...

Quasiquarks in two stream system [PDF]

, 2001
We study the collective quark excitations in an extremely anisotropic system of two interpenetrating streams of the quark-gluon plasma. In contrast to the gluon modes, all quark ones appear to be stable in such a system. Even more, the quark modes in the
