Evidence for an algebra of instantons II
Jihwan Oh, Yehao Zhou
Building on our previous work [2109.01110], we will compute a new kind of instanton partition function. By doing so, we complete a set of building blocks of the instanton par…
OPE of line defects in 5d SCFT
Jihwan Oh
5d ray index is the 5d superconformal index in the presence of a ray-like defect. An elementary ray defect flows to a fundamental Wilson ray in IR gauge theory. In 5d $\mathcal{N}=…
Evidence for an Algebra of Instantons
Michele Del Zotto, Jihwan Oh, Yehao Zhou
In this short note, we present some evidence towards the existence of an algebra of BPS instantons. These are instantonic configurations that govern the partition functions o…
A domain wall in twisted M-theory
Jihwan Oh, Yehao Zhou
We study a four-dimensional domain wall in twisted M-theory. The domain wall is engineered by intersecting D6 branes in the type IIA frame. We identify the classical algebra of ope…
The Global Form of Flavor Symmetries and 2-Group Symmetries in 5d SCFTs
Fabio Apruzzi, Lakshya Bhardwaj, Jihwan Oh +1
2-group symmetries arise when 1-form symmetries and 0-form symmetries of a theory mix with each other under group multiplication. We discover the existence of 2-group symmetries in…
Twisted holography of defect fusions
Jihwan Oh, Yehao Zhou
In the twisted M-theory setting, various types of fusion of M2 and M5 branes induce coproducts between the algebra of operators on M2 branes and the algebra of operators on M5 bran…
On the Quantization of Seiberg-Witten Geometry
Nathan Haouzi, Jihwan Oh
We propose a double quantization of four-dimensional Seiberg-Witten geometry, for all classical gauge groups and a wide variety of matter content. This can be understo…
Feynman diagrams and -deformed M-theory
Jihwan Oh, Yehao Zhou
We derive the simplest commutation relations of operator algebras associated to M2 branes and an M5 brane in the -deformed M-theory, which is a natural set-up for Twisted hologr…
Poisson vertex algebras in supersymmetric field theories
Jihwan Oh, Junya Yagi
A large class of supersymmetric quantum field theories, including all theories with supersymmetry in three dimensions and theories with supersym…
Aspects of -deformed M-theory
Davide Gaiotto, Jihwan Oh
We explore the properties of -deformed M-theory, with particular focus on the background and coupling to -def…
Nonrelativistic String Theory in Background Fields
Jaume Gomis, Jihwan Oh, Ziqi Yan
Nonrelativistic string theory is a unitary, ultraviolet finite quantum gravity theory with a nonrelativistic string spectrum. The vertex operators of the worldsheet theory determin…
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…
2d small N=4 Long-multiplet superconformal block
Filip Kos, Jihwan Oh
We study 2d N=4 superconformal field theories, focusing on its application on numerical bootstrap study. We derive the superconformal block by utilizing the global part of the supe…
An Index for Ray Operators in 5d SCFTs
Chi-Ming Chang, Ori Ganor, Jihwan Oh
We construct an index for BPS operators supported on a ray in five dimensional superconformal field theories with exceptional global symmetries. We compute the representation…
