Generalized Tube Algebras, Symmetry-Resolved Partition Functions, and Twisted Boundary States
Yichul Choi, Brandon C. Rayhaun, Yunqin Zheng
We introduce a class of generalized tube algebras which describe how finite, non-invertible global symmetries of bosonic 1+1d QFTs act on operators which sit at the intersection po…
Noninvertible Symmetry-Resolved Affleck-Ludwig-Cardy Formula and Entanglement Entropy from the Boundary Tube Algebra
Yichul Choi, Brandon C. Rayhaun, Yunqin Zheng
We derive a refined version of the Affleck-Ludwig-Cardy formula for a 1+1d conformal field theory, which controls the asymptotic density of high energy states on an interval transf…
Equivalence Relations on Vertex Operator Algebras, II: Witt Equivalence and Orbifolds
Sven Möller, Brandon C. Rayhaun
When can two strongly rational vertex operator algebras or 1+1d rational conformal field theories (RCFTs) be related by topological manipulations? For vertex operator algebras, the…
Bosonic Rational Conformal Field Theories in Small Genera, Chiral Fermionization, and Symmetry/Subalgebra Duality
Brandon C. Rayhaun
A (1+1)D unitary bosonic rational conformal field theory (RCFT) may be organized according to its genus, a tuple consisting of its central charge and a unitar…
