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…

Bogoliubov phonons in a Bose-Einstein condensate from the one-loop perturbative renormalization group
Niklas Rasch, Aleksandr N. Mikheev, Thomas Gasenzer
Wilson's renormalization-group approach to the weakly-interacting single-component Bose gas is discussed within the symmetry-broken, condensate phase. Extending upon the work by Bi…
