TITLE : Probing Ergodicity In Weakly Non-Integrable Many-Body Systems

ABSTRACT :

In my talk, I would discuss the thermalization dynamics in weakly nonintegrable many-body systems. These systems can restore ergodicity in distinctive ways depending on the range of the interaction network in action space. Action resonances seed chaotic dynamics into the networks. Long-range networks provide well connected resonances with ergodization controlled by the individual resonance chaos time scales. Short-range networks instead yield a dramatic slowing down of ergodization in action space, and lead to rare resonance diffusion.
