Q-operators are 't Hooft lines
Kevin Costello, Davide Gaiotto, Junya Yagi
We study 't Hooft lines in four-dimensional holomorphic-topological Chern-Simons theory. We relate them to Q-operators in the theory of integrable systems. We give a physical inter…
Wilson-'t Hooft lines as transfer matrices
Kazunobu Maruyoshi, Toshihiro Ota, Junya Yagi
We establish a correspondence between a class of Wilson-'t Hooft lines in four-dimensional supersymmetric gauge theories described by circular quivers and transfe…
Disk, interval, point: on constructions of quantum field theories with holomorphic action functionals
Nafiz Ishtiaque, Junya Yagi
Bosonic quantum field theories with holomorphic action functionals are realized by two types of constructions involving supersymmetric quantum field theories, compactified on an in…
Chiral algebras from Ω-deformation
Jihwan Oh, Junya Yagi
In the presence of an -deformation, local operators generate a chiral algebra in the topological-holomorphic twist of a four-dimensional supersymmetric field t…
Chiral Algebras of (0,2) Sigma Models: Beyond Perturbation Theory - II
Meng-Chwan Tan, Junya Yagi
We extend our analysis in [arXiv:0801.4782] and show that the chiral algebras of (0,2) sigma models are totally trivialized by worldsheet instantons for all complete flag manifolds…
Chiral Algebras of (0,2) Sigma Models: Beyond Perturbation Theory
Meng-Chwan Tan, Junya Yagi
We explore the nonperturbative aspects of the chiral algebras of N = (0,2) sigma models, which perturbatively are intimately related to the theory of chiral differential operators…
