**Prerequisites:**

MAT 265 or consent of instructor. Comment: Formally the knowledge of quantum mechanics will not be necessary for understanding of the course, however, I expect that the students are familiar with the main principles of quantum mechanics.

**Course Description:**

Mathematical principles of statistical mechanics and quantum field theory. Topics include classical and quantum lattice systems, variational principles, spontaneous symmetry breaking and phase transitions, second quantization and Fock space, and fundamentals of quantum field theory.
