Non-thermal fixed points of universal sine-Gordon coarsening dynamics
Philipp Heinen, Aleksandr N. Mikheev, Christian-Marcel Schmied +1
We examine coarsening of field-excitation patterns of the sine-Gordon (SG) model, in two and three spatial dimensions, identifying it as universal dynamics near non-thermal fixed p…
Anomalous scaling at non-thermal fixed points of the sine-Gordon model
Philipp Heinen, Aleksandr N. Mikheev, Thomas Gasenzer
We extend the theory of non-thermal fixed points to the case of anomalously slow universal scaling dynamics according to the sine-Gordon model. This entails the derivation of a kin…
Stability analysis of non-thermal fixed points in longitudinally expanding kinetic theory
Aleksandr N. Mikheev, Aleksas Mazeliauskas, Jürgen Berges
We use the Hamiltonian formulation of kinetic theory to perform a stability analysis of non-thermal fixed points in a non-Abelian plasma. We construct a perturbative expansion of t…
