Entropy production in nondegenerate diffusions

Speaker: Renaud Raquépas, CIMS

Location: Warren Weaver Hall 517

Date: Tuesday, October 4, 2022, 1 p.m.

Synopsis:

Entropy production (EP) is a key quantity originating from thermodynamics and statistical physics which quantifies the irreversibility of the time evolution of physical systems. I will start with a general introduction to the different approaches to defining EP. Then, I will focus on the context of nondegenerate diffusions and I will describe the large-deviation properties of EP as time goes to infinity. Time permitting, I will also discuss the behaviour of the corresponding rate function as the intensity of the noise goes to zero.
