Condensation and thermalization of an easy-plane ferromagnet in a spinor Bose gas
Maximilian Prüfer, Daniel Spitz, Stefan Lannig +3
The extensive control of spin makes spintronics a promising candidate for future scalable quantum devices. For the generation of spin-superfluid systems, a detailed understanding o…
Equal-time approach to real-time dynamics of quantum fields
Robert Ott, Torsten V. Zache, Jürgen Berges
We employ the equal-time formulation of quantum field theory to derive effective kinetic theories, first for a weakly coupled non-relativistic Bose gas, and then for a strongly cor…
Thermalization dynamics of a gauge theory on a quantum simulator
Zhao-Yu Zhou, Guo-Xian Su, Jad C. Halimeh +7
Gauge theories form the foundation of modern physics, with applications ranging from elementary particle physics and early-universe cosmology to condensed matter systems. We perfor…
Analog cosmological reheating in an ultracold Bose gas
Aleksandr Chatrchyan, Kevin T. Geier, Markus K. Oberthaler +2
Cosmological reheating describes the transition of the post-inflationary universe to a hot and thermal state. In order to shed light on the underlying dynamics of this process, we…
Finding self-similar behavior in quantum many-body dynamics via persistent homology
Daniel Spitz, Jürgen Berges, Markus K. Oberthaler +1
Inspired by topological data analysis techniques, we introduce persistent homology observables and apply them in a geometric analysis of the dynamics of quantum field theories. As…
Realizing a scalable building block of a U(1) gauge theory with cold atomic mixtures
Alexander Mil, Torsten V. Zache, Apoorva Hegde +6
In the fundamental laws of physics, gauge fields mediate the interaction between charged particles. An example is quantum electrodynamics -- the theory of electrons interacting wit…
