Tensorial TQFT and disentangling modular Walker-Wang models
CMSA EVENTS: CMSA QUANTUM MATTER IN MATH & PHYSICS SEMINAR
When: March 17, 2023
10:00 am - 11:30 am
Where: CMSA, 20 Garden St, G10
Address:
20 Garden Street, Cambridge, MA 02138, United States
Speaker: Andreas Bauer - Freie Universität Berlin
I will introduce simple “tensorial” definitions for many algebraic and categorical structures appearing in the classification of topological phases of matter. Such “tensorial TQFTs” will be defined as maps that associate tensors to geometric/topological objects of some type, subject to gluing axioms. Tensorial TQFTs are very directly related to microscopic physical models in terms of discrete path integrals. I will use those tensorial definitions to construct invertible boundaries which disentangle modular Walker-Wang models.
This seminar offers the option to attend by Zoom. For information on how to join, please see:
