Hydrodynamic attractor in ultracold atoms

K Fujii, T Enss - Physical Review Letters, 2024‏ - APS
The hydrodynamic attractor is a concept that describes universal equilibration behavior in
which systems lose microscopic details before hydrodynamics becomes applicable. We …

Entanglement enabled intensity interferometry in ultrarelativistic ultraperipheral nuclear collisions

JD Brandenburg, H Duan, Z Tu, R Venugopalan… - Physical Review …, 2025‏ - APS
An important tool in studying the subfemtoscale spacetime structure of matter in
ultrarelativistic heavy-ion collisions is Hanbury Brown–Twiss (HBT) intensity interferometry …

Two-dimensional bosonic droplets in a harmonic trap

F Brauneis, AG Volosniev, HW Hammer - arxiv preprint arxiv:2410.00570, 2024‏ - arxiv.org
We investigate a system of bosons in a two-dimensional harmonic trap. In the limit of strong
attractive interactions, the bosons make a droplet insensitive to external confinement. For …

Linearized fluctuating hydrodynamics via random polynomials

F Taghinavaz, G Torrieri - Physical Review D, 2024‏ - APS
We argue that an ensemble of backgrounds best describes hydrodynamic dispersion
relations in a medium with few degrees of freedom and is therefore subject to strong thermal …

Going against the flow: Revealing the QCD degrees of freedom in hadronic collisions

C Bierlich, P Christiansen, G Gustafson… - arxiv preprint arxiv …, 2024‏ - arxiv.org
In collisions between heavy nuclei, such as those at the Large Hadron Collider (LHC) at
CERN, hydrodynamic models have successfully related measured azimuthal momentum …

Superfluids in expanding backgrounds and attractor times

GK Buza, T Mitra, A Soloviev - arxiv preprint arxiv:2410.01892, 2024‏ - arxiv.org
We determine the behavior of an out-of-equilibrium superfluid, composed of a $ U (1) $
Goldstone mode coupled to hydrodynamic modes in a M\" uller-Israel-Stewart theory, in …

Fluid-dynamic description of heavy quarks in the quark-gluon plasma

F Capellino - 2024‏ - archiv.ub.uni-heidelberg.de
Heavy quarks (ie charm and beauty) are powerful tools to characterize the quark-gluon
plasma (QGP) produced in heavy-ion collisions. Although they are initially produced out of …

Stochastic Approaches and the Physics of Ultracold Fermions: From Lattice Simulations to Machine Learning

M Bauer - 2024‏ - archiv.ub.uni-heidelberg.de
This thesis investigates fermionic ultracold atom systems in reduced dimensions using
stochastic and lattice-based methods. One particular focus of the current work lies in …

[HTML][HTML] From few-to many-body physics in low-dimensional quantum gases

F Brauneis‏ - tuprints.ulb.tu-darmstadt.de
Macroscopic systems exhibit complex behavior that cannot be understood by studying their
few-body components alone. A key challenge in modern physics is to uncover how many …
