Chiral Tube Algebras I: Topological Defect Lines, Twisted Modules, and Finite Gauging
Nathan Benjamin, Ho Tat Lam, Conghuan Luo
Chiral algebras and topological defect lines (TDLs) represent two complementary notions of symmetry in 2d conformal field theories. In this paper, we introduce chiral tube algebras…
Generalized Symmetries and Deformations of Symmetric Product Orbifolds
Nathan Benjamin, Suzanne Bintanja, Yu-Jui Chen +3
We construct generalized symmetries in two-dimensional symmetric product orbifold CFTs for a generic seed CFT . These symmetries are more…
Towards an Effective String Theory for the flux tube
Andreas Athenodorou, Sergei Dubovsky, Conghuan Luo +1
The quest to develop an effective string theory capable of describing the confining flux tube has been a longstanding objective within the theoretical physics community. Recent lat…
Confining Strings and the Worldsheet Axion from the Lattice
Andreas Athenodorou, Sergei Dubovsky, Conghuan Luo +1
We present a major update on the spectrum of closed flux tubes in gauge theories. We measure the excitation spectrum of confining strings wound around a spatial dim…
Confining Strings and Glueballs in Gauge Theories
Andreas Athenodorou, Sergei Dubovsky, Conghuan Luo +1
Effective string theory has shown its universal power in the prediction of the spectrum of low-lying excited states of confining strings. Here we study confining flux tubes in $\ma…
Gauging Non-Invertible Symmetries: Topological Interfaces and Generalized Orbifold Groupoid in 2d QFT
Oleksandr Diatlyk, Conghuan Luo, Yifan Wang +1
Gauging is a powerful operation on symmetries in quantum field theory (QFT), as it connects distinct theories and also reveals hidden structures in a given theory. We initiate a sy…
Excitations of Ising Strings on a Lattice
Andreas Athenodorou, Sergei Dubovsky, Conghuan Luo +1
The 3d Ising model in the low temperature (ferromagnetic) phase describes dynamics of two-dimensional surfaces -- domain walls between clusters of parallel spins. The Kramers--Wann…
Casimir Energy and Modularity in Higher-dimensional Conformal Field Theories
Conghuan Luo, Yifan Wang
An important problem in Quantum Field Theory (QFT) is to understand the structures of observables on spacetime manifolds of nontrivial topology. Such observables arise naturally wh…
