Theory of phase transitions
This course discusses theory of fluctuational phenomena related to macroscopic degrees of freedom. Besides critical phenomena near the secondorder phase transitions and critical points, we will consider various phases of condensed matter in which fluctuations play an important role. The formulated theory of dynamic fluctuations will be applicable both to equilibrium and nonequilibrium systems. We will use the formalism of functional integrals, diagrammatic technique, renormalizationgroup procedure, scaling relations, Langevin forces, analysis of the tails of the probability distribution function. Lectures are accompanied by problems, solution of which facilitates better understanding of lectures.
