Dynamical fluctuations, phase transitions, and large deviations

Sommaire:

A common theme in statistical physics is that we can better understand systems' behaviour by analysing their fluctuations, and the probabilities of rare events, in which the system behaves in an unusual way. Recently, there has been a focus on dynamical fluctuations, and a particular type of rare event known as large deviations. I will explain what these events are, and give some examples where they reveal interesting behaviour, including phase transitions in one-dimensional systems [1,2], the coupling of structure with dynamics in glasses [3], and applications to shear flow [4].
