Résumé |
Nonthermal fixed points are universal, attractive phenomena arising in far-from-equilibrium systems. They have been studied in different physical systems, such as theoretical models of heavy-ion conditions and cold-atom experiments. In analogy to strongly-coupled CFTs or black holes, one can study the attractive nature of nonthermal fixed points by calculating their quasinormal mode spectra. These give rise to a tower of powerlaw decaying excitations. By making the connection between this technique used in black-hole physics, I try to bridge the field of far-from-equilibrium dynamics and strongly-coupled thermalization |
