Far from equilibrium hydrodynamics of nonthermal fixed points
Jürgen Berges, Gabriel S. Denicol, Michal P. Heller +1
Nonthermal fixed points are paradigmatic far-from-equilibrium phenomena of relevance to high-energy physics, cosmology, and cold atomic gases. We propose that, despite their intrin…
Coupling renormalization flow in the strongly interacting regime of an asymptotically free quantum field theory in four dimensions
Jürgen Berges, Razvan Gurau, Hannes Keppler +1
We consider a scalar quantum field theory with global symmetry in four Euclidean dimensions and solve it numerically in closed form in the large-N limit. For imaginary tet…
Prescaling relaxation to nonthermal attractors
Michal P. Heller, Aleksas Mazeliauskas, Thimo Preis
We study how isotropic and homogeneous far-from-equilibrium quantum systems relax to nonthermal attractors, which are of interest for cold atoms and nuclear collisions. We demonstr…
Asymptotic freedom in a strongly interacting scalar quantum field theory in four Euclidean dimensions
Jürgen Berges, Razvan Gurau, Thimo Preis
We show that scalar quantum field theory in four Euclidean dimensions with global symmetry and imaginary tetrahedral coupling is asymptotically free and bounded from below…
