On Symmetry-Compatible Superselection Structures for Product States in 2D Quantum Spin Systems
Matthew Corbelli
We study superselection sectors in two-dimensional quantum spin systems with an on-site action of a compact abelian group . Naaijkens and Ogata (2022) arXiv:2102.07707 showed th…

Tensor category describing anyons in the quantum Hall effect and quantization of conductance
Sven Bachmann, Matthew Corbelli, Martin Fraas +1
In this study, we examine the quantization of Hall conductance in an infinite plane geometry. We consider a microscopic charge-conserving system with a pure, gapped infinite-volume…
