2020 Theory Winter School

2020 Theory Winter School was held on January 6-10, 2020. This year's School focused on "Quantum Matter Without Quasiparticles", a subject inspired by recent developments in condensed matter physics and beyond. These development shed new light on open questions of quantum criticality, unconventional superconductivity, and new types of topological phases of matter. The tentative topics of the school include electron transport without quasiparticles, Sachdev-Ye-Kitaev models, novel phases in twisted bilayer graphene, fracton topological phases, deconfined quantum criticality, and many-body localization.
