"Typicality and Fluctuations: A different way to look at Quantum Statistical Mechanics"

Complex phenomena such as the characterization of the properties and the dynamics of many body systems can be approached from different perspectives, which lead to physical theories of completely different characters. A striking example of this is the duality, for a given physical system, between its thermodynamical characterization and the pure mechanical description. Finding a connection between these different approaches requires the introduction of suitable statistical tools. While classical statistical mechanics represents a conceptually clear framework, some problems arise if quantum mechanics is assumed as fundamental theory. In this talk, after a general introduction to the subject for non-experts, we shall discuss the emergence of thermodynamic properties from the underlying quantum dynamics.
