Ph 127 ab - Statistical Physics of Interacting Systems, Phases, and Phase Transitions

Ph 127 ab

Statistical Physics of Interacting Systems, Phases, and Phase Transitions

9 units (4-0-5)   |  first, second terms
Prerequisites: Ph 12 c or equivalent; quantum mechanics at the level of Ph 125 ab is required for Ph 127 b; may be taken concurrently.

An advanced course in statistical physics that focuses on systems of interacting particles. Part a will cover interacting gases and spin models of magnetism, phase transitions and broken symmetries, classical field theories, and renormalization group approach to collective phenomena. Part b will introduce the path-integral based quantum to classical statistical mechanics mapping, as well as dualities and topological-defects descriptions, with applications to magnets, superfluids, and gauge field theories.
