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…
