This course covers the principles and methods of equilibrium statistical mechanics for applications to chemical physics problems. The lectures will be divided into three parts: (1) A short review of thermodynamics principles. (2) The concepts of ensemble theory and the applications to gas, liquid, and solid systems. The Landau theory of phase transition will be discussed. (3) The final part will introduce the phase transition dynamics and the theory of Brownian motion.

Planned topics: laws of thermodynamics, thermal equilibrium and temperature, ensemble theory, entropy, non-interacting systems (gas and solid), chemical equilibrium, Ising models, imperfect gases, ionic solutions, Landau theory, dynamics of phase transition, Langevin equation and Brownian motion.
