Thermalization in QFT: from nuclear collisions to cold atoms and back
I will give an overview of new results on the attractor-based picture of thermalization in QFT. I will start with a discussion what are the hydrodynamic attractors, why they were born in the context of nuclear collisions at RHIC and LHC and what can we learn about them in cold atom experiments. Subsequently I will focus on nonthermal attractors, discuss new results explaining their attractive nature in terms of quasinormal mode spectra and show what can be learnt about them using intuitions from hydrodynamic attractors. Based on 2510.15016 with Werthmann, 2502.01622 with De Lescluze and 2504.18754 with Berges, Denicol and Preis.
