Ginzburg-Landau Theory for Non-Invertible Symmetry-Breaking Transitions
Vibhu Ravindran, Luisa Eck, Xie Chen
Recently, a generalized Landau paradigm has been proposed, in which a broad class of "unconventional" phase transitions lying beyond the original symmetry-breaking framework of Lan…

Non-invertible symmetry enriched string net topological orders
Luisa Eck, Peter Huston, Kyle Kawagoe +1
We propose a definition of a non-invertible symmetry enriched topological order (NI-SETO), and we implement our definition for string net models. We do so in two ways, using full i…

3d Conformal Field Theories via Fuzzy Sphere Algebra
Luisa Eck, Zhenghan Wang
Fuzzy sphere models conjecturally realize 3d CFTs in small systems of spinful fermions, but why they work so well is still not fully understood. Their Hamiltonians are built from e…
