Fortuity on the conifold

Jaehyeok Choi, Sunjin Choi, Seok Kim

To study the BPS black hole states in typical $N = 1$ AdS $_{5}$ /CFT $_{4}$ models, we formulate a classical cohomology problem in the Klebanov-Witten theory, which is defined at…

Towards OSV in AdS

Nikolay Bobev, Sunjin Choi, Junho Hong +1

We use supersymmetric localization for 3d $N = 2$ SCFTs to establish a relation of the form $Z_{S^{1} \times S^{2}} \sim ∣ Z_{S_{b}^{3}} ∣^{2}$ between the superconformal index and the…

On holography with ADE singularities

Sunjin Choi, Yuji Tachikawa

We study aspects of the AdS/CFT correspondence for $N = 4$ $U (N)$ super Yang-Mills theory on $S^{3} /Γ$ , where $Γ \subset S U (2)$ is a finite subgroup, leading to an ADE singula…

Supersymmetric Grey Galaxies, Dual Dressed Black Holes and the Superconformal Index

Sunjin Choi, Diksha Jain, Seok Kim +5

Motivated by the recent construction of grey galaxy and Dual Dressed Black Hole solutions in $A d S_{5} \times S^{5}$ , we present two conjectures relating to the large $N$ entropy of supe…

Sunjin Choi, Diksha Jain, Seok Kim +4

Charged Black holes in $A d S_{5} \times S^{5}$ suffer from superradiant instabilities over a range of energies. Hairy black hole solutions (constructed within gauged supergravity) have…

Jaehyeok Choi, Sunjin Choi, Seok Kim +2

We study new cohomologies for the BPS operators of the $N = 4$ Yang-Mills theory with $S U (3)$ and $S U (4)$ gauge groups, to better understand the black hole microstates. We…

Sunjin Choi, Seunggyu Kim, Jaewon Song

We study the large $N$ limit of the matrix models associated with the superconformal indices of four-dimensional $N = 1$ superconformal field theories. We find that for a l…

Supersymmetric Cardy Formula and the Weak Gravity Conjecture in AdS/CFT

Minseok Cho, Sunjin Choi, Ki-Hong Lee +1

The Weak Gravity Conjecture (WGC) in anti-de Sitter spacetime (AdS) asserts the existence of an operator in the boundary conformal field theory (CFT) whose scaling dimension-to-cha…

Towards quantum black hole microstates

Sunjin Choi, Seok Kim, Eunwoo Lee +2

We study the cohomology of local BPS operators in $N = 4$ Yang-Mills theory. The finite $N$ cohomologies consist of the graviton part (subject to the stringy exclusion prin…

Large $N$ Superconformal Indices for 3d Holographic SCFTs

Nikolay Bobev, Sunjin Choi, Junho Hong +1

We study a limit of the superconformal index of the ABJM theory on $S^{1} \times S^{2}$ in which the size of the circle is much smaller than the radius of the two-sphere. We derive clos…

The shape of non-graviton operators for $S U (2)$

Sunjin Choi, Seok Kim, Eunwoo Lee +1

The BPS spectrum of AdS/CFT exhibits multi-gravitons at low energies, while having black hole states at higher energies. This can be studied concretely in AdS $_{5}$ /CFT $_{4}$ in terms…

From giant gravitons to black holes

Sunjin Choi, Seok Kim, Eunwoo Lee +1

We study AdS $_{5}$ black holes from a recently suggested giant graviton expansion formula for the index of $U (N)$ maximal super-Yang-Mills theory. We compute the large $N$ entropy at…

Supersymmetric Spectral Form Factor and Euclidean Black Holes

Sunjin Choi, Seok Kim, Jaewon Song

The late-time behavior of spectral form factor (SFF) encodes the inherent discreteness of a quantum system, which should be generically non-vanishing. We study an index analog of t…

Infrared phases of 3D Class R theories

Sunjin Choi, Dongmin Gang, Hee-Cheol Kim

We study the IR phases of 3D class R theories associated with closed non-hyperbolic 3-manifolds. Non-hyperbolic 3-manifolds can be obtained by performing Dehn fillings on 1-cusped…
