Black holes and Large $N$ complex saddles in 3D-3D correspondence

Sunjin Choi, Dongmin Gang, Nakwoo Kim

We study the large $N$ sign oscillation of the twisted indices for 3D theories of class $R$ obtained from M5-branes wrapped on a hyperbolic 3-manifold. Holographically,…

Universal 3d Cardy Block and Black Hole Entropy

Sunjin Choi, Chiung Hwang

We discuss the Cardy limit of 3d supersymmetric partition functions which allow the factorization into the hemisphere indices: the generalized superconformal index, the refined top…

Quantum vortices, M2-branes and black holes

Sunjin Choi, Chiung Hwang, Seok Kim

We study the partition functions of BPS vortices and magnetic monopole operators, in gauge theories describing $N$ M2-branes. In particular, we explore two closely related methods…

Comments on deconfinement in AdS/CFT

Sunjin Choi, Joonho Kim, Seok Kim +1

We study the index of $N = 4$ Yang-Mills theory on $S^{3} \times R$ . We argue that the index should undergo a large $N$ deconfinement phase transition, by computing an…

Entropy functions of BPS black holes in AdS $_{4}$ and AdS $_{6}$

Sunjin Choi, Chiung Hwang, Seok Kim +1

We find the entropy functions of supersymmetric black holes in AdS $_{4}$ and AdS $_{6}$ with electric charges and angular momenta. Extremizing these functions, one obtains the entropies…
