Nonthermal fixed point for massless scalar field theories
Viktoria Noel, Chuang Huang, Aleksandr N. Mikheev +1
We compute universal scaling exponents and scaling functions for massless scalar field theories far from equilibrium. Using a large- expansion to next-to-leading order, we inves…
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…
Dimensional crossover for universal scaling far from equilibrium
Lasse Gresista, Torsten V. Zache, Jürgen Berges
We perform a dynamical finite-size scaling analysis of a nonequilibrium Bose gas which is confined in the transverse plane. Varying the transverse size, we establish a dimensional…
Schwinger pair production and string breaking in non-Abelian gauge theory from real-time lattice improved Hamiltonians
D. Spitz, J. Berges
Far-from-equilibrium dynamics of SU(2) gauge theory with Wilson fermions is studied in 1+1 space-time dimensions using a real-time lattice approach. Lattice improved Hamiltonians a…
Universal self-similar scaling of spatial Wilson loops out of equilibrium
J. Berges, M. Mace, S. Schlichting
We investigate strongly correlated non-Abelian plasmas out of equilibrium. Based on numerical simulations, we establish a self-similar scaling property for the time evolution of sp…
Universal scaling of unequal-time correlation functions in ultracold Bose gases far from equilibrium
A. Schachner, A. Piñeiro Orioli, J. Berges
We explore the far-from-equilibrium dynamics of Bose gases in a universal regime associated to nonthermal fixed points. While previous investigations concentrated on scaling functi…
