Watch a physics seminar from the Topological Quantum Matter series where Princeton University researcher Jonah Herzog-Arbeitman explores exact solutions in flat band Hubbard models. Delve into the fascinating world of strongly coupled physics, focusing on flat bands found in structures like the kagome lattice and twisted bilayer graphene. Learn how these systems exhibit unconventional behavior in multi-orbital cases, particularly regarding superconductivity in situations with zero Fermi velocity. Discover how exact solvability of groundstates and low-energy excitations in attractive Hubbard models provides unique insights into quantum geometry and challenges traditional BCS theory understanding. Gain a microscopic perspective on strong coupling theory through this detailed mathematical and theoretical physics presentation delivered at Harvard CMSA.
