Hauptseminar Thermalisierung
Hauptseminar "Classical and Quantum Equilibration Problems: How do Nonequilibrium Systems Relax?"

Veranstalter:
von Delft, Marquardt, Kehrein, Yevtushenko

Mittwoch, 9:00 -10:00 Uhr, Theresienstr. 37, Raum A 450



One fundamental assumption in physics is that systems relax to a thermal state after waiting long enough. Most theoretical work simply starts out from this assumption. However, the question under which conditions this assumption is valid dates back to Boltzmann and the very foundations of Statistical Mechanics. It has gained new importance or quantum systems due to beautiful experiments in ultracold atom gases that challenge our preconceptions. In this seminar we will explore this active research topic starting from the Fermi-Pasta-Ulam problem and the Boltzmann equation until today's experiments in atom gases.



Das Hauptseminar beginnt immer um 9:00 Uhr.
