A defect TQFT approach to fractons
ORAL
Abstract
We explore fracton phases from the perspective of topological quantum field theories. We argue that type I and type II gapped fracton models can be realized by a network of defects embedded into various 3+1D topological quantum field theories. The idea is that subdimensional excitations characteristic of fracton phases can appear due to mobility restrictions imposed by the defect network. We explicitly construct many well known examples of fracton phases and a few new models using the defect construction. As a byproduct the defect construction provides a generalized membrane-net condensate picture of fracton phases.
