The eigenstate thermalization hypothesis, hydrodynamics and the appearance of thermal behaviour in quantum many-body systems

The eigenstate thermalization hypothesis is a cornerstone in the theoretical description of the process of equilibration of many-body quantum systems. In this seminar I will show that it is a very fruitful exercise to combine it with the fact that the underlying energy dynamics of the system is diffusive (or characterized by another transport mechanism). After presenting our results [1], I will conclude the seminar with a discussion of the process of thermalization with the tools of quantum information [2].
