Modular commutator in gapped quantum many-body systems
Isaac H. Kim, Bowen Shi, Kohtaro Kato +1
In arXiv:2110.06932, we argued that the chiral central charge -- a topologically protected quantity characterizing the edge theory of a gapped (2+1)-dimensional system -- can be ex…

Chiral central charge from a single bulk wave function
Isaac H. Kim, Bowen Shi, Kohtaro Kato +1
A -dimensional gapped quantum many-body system can have a topologically protected energy current at its edge. The magnitude of this current is determined entirely by the tem…
