Towards the end of my PhD, quite a while ago, I was working on extracting the symmetry-enriched topological order that occurs when the gauge charges of a finite group are condensed in a topological phase of matter.
In our new work we propose that after a general condensation in a topological phase the resulting topological order is enriched by a noninvertible symmetry hypergroup.
Thanks to Lea, Clement, Ed, and Campbell for the fun collaboration.

Excited to share our new work led by fantastic undergraduate research student Cassie Hopkin.
We show that many translation invariant qLDPC codes can be viewed as compactifications of a single parent fracton code that is local in a higher dimension.

Curiously, a similar calculation could be done for general condensations that were not related to finite groups. But it was unclear if one could make sense of symmetry-enrichment in the absence of a finite group... Until now.

Quantum error-correcting codes with translation symmetry and local checks have been studied extensively, leading to a wide variety of fracton codes in three or more dimensions which lack a complete un...
