Talk Title:  “Landau Theory of Phase Transitions”

Abstract:

Landau theory has been an extraordinary useful tool for understanding phase transitions such as melting and the onset of magnetism, superfluidity and superconductivity. It explained how non-analyticity can appear in theories that are constructed from analytical functions, how the symmetry of a system can be broken spontaneously, and how a gauge field can acquire mass by coupling to a Higgs field. The colloquium will review some of this history and then turn to the Landau theory of orientational phase transitions in liquid crystals, glasses, and viral capsids.
