Prethermalization and thermalization in models with weak integrability breaking

Regular Seminar Fabian Essler (Oxford U.)

room K4.31

I consider the the effect of weak integrability breaking interactions on the non-equilibrium time evolution in many-particle systems. Using a class of weakly interaction fermion models as an example, I argue that there exists a time window in which the system relaxes locally to a non-equilibrium meta-stable state, before it eventually thermalizes.
