CONTRIBUTED TALK (25min +5)

The force between particles is one of the most elementary concepts from condensed-matter physics to high-energy physics. Not only the fundamental interaction mediated by gauge bosons but also the induced interaction between quasiparticles plays an essential role in modern physics.
Recently, impurities in superfluids, called polarons, have been attracting much attention in ultracold atom...

180. Stable and unstable perturbations in universal scaling phenomena far from equilibrium

Mr Thimo Preis (Heidelberg University )

CONTRIBUTED TALK (25min +5)

We study the dynamics of perturbations around nonthermal fixed points associated to universal scaling phenomena in quantum many-body systems far from equilibrium. For an N -component scalar quantum field theory in 3+1 space-time dimensions, we determine the stability scaling exponents using a self-consistent large-N expansion to next-to-leading order. Our analysis reveals the presence of both...

187. Extending the fluid dynamic description of heavy-ions collisions to times before the collision

Mr Andreas Kirchner (ITP Heidelberg)

18/11/2022, 09:30

CONTRIBUTED TALK (25min +5)

It is well established that the late states of a high energy nuclear collision can be described in terms of relativistic fluid dynamics. An open problem in this context is how the actual collision and the early time dynamics directly after it can be described. Phenomenological models are currently employed here and they have several parameters that need to be fitted to experimental data.

179. Theory of the magnetic moments and hyperfine splitting of ³He+

Bastian Sikora (Max Planck Institute for Nuclear Physics)

CONTRIBUTED TALK (25min +5)

In an external magnetic field, the ground state of the $^3$He$^+$ ion is split into into four sublevels due to the combined hyperfine splitting and Zeeman effect. By measuring transition frequencies between these sublevels, it is possible to determine the $g$-factor of the bound electron, the ground-state hyperfine splitting as well as the shielded magnetic moment of the nucleus [1].
In this...
