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 $S^{3} / I^$ , where $I^ \subset S U (2)$ is a finite subgroup, leading to an ADE singu…

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…

Dual Dressed Black Holes as the end point of the Charged Superradiant instability in $N = 4$ Yang Mills

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…

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…

Exact QFT duals of AdS black holes

Sunjin Choi, Saebyeok Jeong, Seok Kim +1

We construct large $N$ saddle points of the matrix model for the $N = 4$ Yang-Mills index dual to the BPS black holes in $A d S_{5} \times S^{5}$ , in two different setups. When th…
