Symmetry Protected Topological Phases, Cobordism, and QCA - IPAM at UCLA

Explore an in-depth lecture on Symmetry Protected Topological (SPT) phases, cobordism, and Quantum Cellular Automata (QCA) presented by Lukasz Fidkowski from the University of Washington. Delve into the cobordism classification of SPT phases, which extends the group cohomology classification, following Anton Kapustin's continuum-based approach. Gain insights into the connection between beyond cohomology phases and obstacles in implementing the Else-Nayak truncation procedure on lattices. Discover how these concepts relate to QCA in this comprehensive talk from IPAM's Graduate Summer School on Mathematics of Topological Phases of Matter.
