Lectures: Monday & Wednesday, 10:00 am -11:20 pm
Where: Room: LG72 Tech Institute -- Canvas

This is a graduate-level course on nonequilibrium statistical physics and phase transitions covering topics ranging from Brownian motion, stochastic dynamics, Langevin theory and Fokker-Planck dynamics. This quarter will cover fluctuations in thermodynamic systems, space-time correlations of fluctuations, origins of dissipation, linear response theory and the fluctuation-dissipation theorem. The course will also include selected topics on spontaneous symmetry breaking and the theory of second-order phase transitions.

Pre-requisites: undergraduate-level statistical physics and quantum mechanics.
