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}=…
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…
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…
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…
