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…
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…
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…
Equivalence Relations on Vertex Operator Algebras, I: Genus
Sven Möller, Brandon C. Rayhaun
In this first of a series of two papers, we investigate two different equivalence relations obtained by generalizing the notion of genus of even lattices to the setting of vertex o…
Rationality in Four Dimensions
Leonardo Rastelli, Brandon C. Rayhaun
By leveraging the physics of the Higgs branch, we argue that the conformal central charges and of an arbitrary 4d superconformal field theory (SCFT) are rational numb…
Remarks on Boundaries, Anomalies, and Noninvertible Symmetries
Yichul Choi, Brandon C. Rayhaun, Yaman Sanghavi +1
What does it mean for a boundary condition to be symmetric with respect to a non-invertible global symmetry? We discuss two possible definitions in 1+1d. On the one hand, we call a…
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…
Classification of Unitary RCFTs with Two Primaries and Central Charge Less Than 25
Sunil Mukhi, Brandon C. Rayhaun
We classify all two-dimensional, unitary, rational conformal field theories with two primaries, central charge , and arbitrary Wronskian index. In mathematical parlance, we c…
Higher-Form Subsystem Symmetry Breaking: Subdimensional Criticality and Fracton Phase Transitions
Brandon C. Rayhaun, Dominic J. Williamson
Subsystem symmetry has emerged as a powerful organizing principle for unconventional quantum phases of matter, most prominently fracton topological orders. Here, we focus on a spec…
Fractons and exotic symmetries from branes
Hao Geng, Shamit Kachru, Andreas Karch +2
The emerging study of fractons, a new type of quasi-particle with restricted mobility, has motivated the construction of several classes of interesting continuum quantum field theo…
