Bosonization of Fermi Surfaces and Coadjoint Orbits

Join this physics seminar where Dam Thanh Son from the University of Chicago presents a novel field-theoretical reformulation of Landau Fermi liquid theory, exploring the bosonization of Fermi surfaces and coadjoint orbits. Discover how the space of low-energy states in a Fermi liquid connects to coadjoint orbits of canonical transformations, leading to a nonlinear bosonized description. Learn about the Berry phase of the Fermi surface and its relationship to the Kirillov-Kostant-Souriau symplectic form, while understanding how this local effective field theory encompasses both linear and nonlinear effects in Landau's Fermi liquid theory. Explore potential extensions and applications of this groundbreaking theoretical approach that provides a fresh perspective on one of condensed matter physics' fundamental theories.
