Classification of 2D Fermionic Systems with a Flavor Symmetry
Chi-Ming Chang, Jin Chen, Fengjun Xu
We classify superfusion categories describing two-dimensional fermionic systems equipped with the universal fermion-parity symmetry, implemented by a topological defect line (TDL)…
-matrix in permutation orbifolds
Chongying Dong, Feng Xu, Nina Yu
For a fixed positive integer , any element of the permutation group acts on the tensor product vertex operator algebra in the obvious way. In this pa…
The Hitchhiker's Guide to 4d Superconformal Field Theories
Mohammad Akhond, Guillermo Arias-Tamargo, Alessandro Mininno +4
Superconformal field theory with supersymmetry in four dimensional spacetime provides a prime playground to study strongly coupled phenomena in quantum field theory…
S-matrix in orbifold theory
Chongying Dong, Li Ren, Feng Xu
The restricted -matrix of is determined for any regular vertex operator algebra and finite automorphism group of As an application, the -matrices for cycli…
On TCS manifolds and 4D Emergent Strings
Fengjun Xu
In this note, we study the Swampland Distance Conjecture in TCS manifold compactifications of M-theory. In particular, we are interested in testing a refined version -- the E…
Von Neumann Entropy in QFT
Roberto Longo, Feng Xu
In the framework of Quantum Field Theory, we provide a rigorous, operator algebraic notion of entanglement entropy associated with a pair of open double cones …
