Split Heun functions via blown-up surface defects
Saebyeok Jeong, Tommaso Pedroni
We study resonant solutions of the Heun equation and its confluent limits that arise in the Nekrasov-Shatashvili (NS) limit of four-dimensional gau…
Bispectral duality and separation of variables from surface defect transition
Saebyeok Jeong, Norton Lee
We study two types of surface observables the -observables and the -observables of the 4d -quiver gauge theory obtained…
di-Langlands correspondence and extended observables
Saebyeok Jeong, Norton Lee, Nikita Nekrasov
We explore the using the four dimensional super-QCD. Surface defects and surface observables play the crucial role.…
Parallel surface defects, Hecke operators, and quantum Hitchin system
Saebyeok Jeong, Norton Lee, Nikita Nekrasov
We examine two types of half-BPS surface defects regular monodromy surface defect and canonical surface defect in four-dimensional gauge theory with supersy…
Exact QFT duals of AdS black holes
Sunjin Choi, Saebyeok Jeong, Seok Kim +1
We construct large saddle points of the matrix model for the Yang-Mills index dual to the BPS black holes in , in two different setups. When th…
Intersecting defects in gauge theory, quantum spin chains, and Knizhnik-Zamolodchikov equations
Saebyeok Jeong, Norton Lee, Nikita Nekrasov
We propose an interesting BPS/CFT correspondence playground: the correlation function of two intersecting half-BPS surface defects in four-dimensional supersymmetri…
The Yang-Mills duals of small AdS black holes
Sunjin Choi, Saebyeok Jeong, Seok Kim
We study the large matrix model for the index of 4d Yang-Mills theory and its truncations to understand the dual AdS black holes. Numerical studies of the t…
Riemann-Hilbert correspondence and blown up surface defects
Saebyeok Jeong, Nikita Nekrasov
The relationship of two dimensional quantum field theory and isomonodromic deformations of Fuchsian systems has a long history. Recently four-dimensional gauge theo…
A note on chiral trace relations from qq-characters
Saebyeok Jeong, Xinyu Zhang
We study chiral operators in four-dimensional N=2 supersymmetric gauge theories. We provide a general procedure to derive the exact relations among the vacuum expectation values of…
New quantum toroidal algebras from 5D instantons on orbifolds
Jean-Emile Bourgine, Saebyeok Jeong
Quantum toroidal algebras are obtained from quantum affine algebras by a further affinization, and, like the latter, can be used to construct integrable systems. These algebras als…
SCFT/VOA correspondence via -deformation
Saebyeok Jeong
We investigate an alternative approach to the correspondence of four-dimensional superconformal theories and two-dimensional vertex operator algebras, in the framew…
Opers, surface defects, and Yang-Yang functional
Saebyeok Jeong, Nikita Nekrasov
We explore the non-perturbative Dyson-Schwinger equations obeyed by the partition functions of the -deformed supersymmetric linear quiver gauge theories in…
BPZ equations for higher degenerate fields and nonperturbative Dyson-Schwinger equations
Saebyeok Jeong, Xinyu Zhang
In the two-dimensional Liouville conformal field theory, correlation functions involving a degenerate field satisfy partial differential equations due to the decoupling of the null…
Splitting of surface defect partition functions and integrable systems
Saebyeok Jeong
We study Bethe/gauge correspondence at the special locus of Coulomb moduli where the integrable system exhibits the splitting of degenerate levels. For this investigation, we consi…
