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…
Condensation and prescaling in spatial Polyakov loop correlations far from equilibrium
Daniel Spitz, Kirill Boguslavski, Thimo Preis
The far-from-equilibrium dynamics of spatial Polyakov loop correlations, which provide gauge-invariant observables akin to effective particle numbers for gluon plasmas, are investi…
Droplets of Bosons at a Narrow Resonance
Ke Wang, Thimo Preis, Dam Thanh Son
We consider bosons interacting through a narrow -wave resonance. Such a resonance is characterized by an infinite scattering length and a large and negative effective range $r_0…
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…
Stable and unstable perturbations in universal scaling phenomena far from equilibrium
Thimo Preis, Michal P. Heller, Jürgen Berges
We study the dynamics of perturbations around nonthermal fixed points associated to universal scaling phenomena in quantum many-body systems far from equilibrium. For an N-componen…
