Renormalised thermodynamics for Bose gases from low to critical temperatures
Michael H. Heinrich, Alexander Wowchik, Jürgen Berges
We compute thermodynamic properties of dilute Bose gases using non-perturbative approximations of the two-particle irreducible (2PI) effective action. It is shown how to systematic…
Extracting the symmetries of nonequilibrium quantum many-body systems
Aleksandr N. Mikheev, Viktoria Noel, Ido Siovitz +3
Symmetries play a pivotal role in our understanding of the properties of quantum many-body systems. While there are theorems and a well-established toolbox for systems in thermal e…
Scalable cold-atom quantum simulator for two-dimensional QED
Robert Ott, Torsten V. Zache, Fred Jendrzejewski +1
We propose a scalable analog quantum simulator for quantum electrodynamics (QED) in two spatial dimensions. The setup for the U(1) lattice gauge field theory employs inter-species…
Schwinger pair production with ultracold atoms
V. Kasper, F. Hebenstreit, M. Oberthaler +1
We consider a system of ultracold atoms in an optical lattice as a quantum simulator for electron-positron pair production in quantum electrodynamics (QED). For a setup in one spat…
