Program on Anomalies, Topology and Quantum Information in Field Theory and Condensed Matter Physics

The Landau paradigm for characterizing phase transitions is living a renaissance at present. This interest has grown in parallel on several forefronts of research – including condensed matter physics, topological quantum field theory, quantum field theory in its various axiomatic approaches (e.g. Euclidean path integrals, bootstrap, algebraic), and quantum information. In all these fronts, the concepts of generalized symmetries, generalized order parameters and anomalies have played a prominent role, and have allowed a conceptual unification of different problems in the various fields. The dream is that these concepts might provide a unified perspective on the classification of general phases of matter.

This two-week program brings together researchers from all these different disciplines, so that recent discoveries can be shared and critiqued, and the next steps can be envisioned. In the first week, five lecturers, Fiona Burnell, Horacio Casini, Paul Fendley, John McGreevy, and Shinsei Ryu will review recent developments in the field, and there will be open discussions. Topics will include: generalized symmetries in condensed matter physics, topological field theories, quantum information and symmetries in quantum field theory, experimental developments and symmetries in anyon models. The second week will host a standard conference event with seminars by invited speakers.
