The shape of non-graviton operators for SU(2) Open
A bstract 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 of classical cohomologies, even in the quantum regim…

Towards quantum black hole microstates Open
A bstract We study the cohomology of local BPS operators in $$ \mathcal{N} $$ = 4 Yang-Mills theory. The finite N cohomologies consist of the graviton part (subject to the stringy exclusion principle) and the rest which may describe blac…

Supersymmetric instantonic D1-branes in AdS5×S5 background Open
A bstract According to the covariant open superstring description of 1/2-BPS D-branes in the AdS 5 ×S 5 background, there are two kinds of purely instantonic D-branes. One is the well known D(-1)-brane or D-instanton, and another is the D1…

Monopole deformations of 3d Seiberg-like dualities with adjoint matters Open
We propose new 3d $\mathcal{N}=2$ Seiberg-like dualities by considering various monopole superpotential deformations on 3d $\mathcal{N}=2$ $U(N_c)$ SQCDs with fundamental and adjoint matter fields. We provide nontrivial evidence of these n…

6D strings and exceptional instantons Open
We propose new ADHM-like methods to compute the Coulomb branch instanton\npartition functions of 5d and 6d supersymmetric gauge theories, with certain\nexceptional gauge groups or exceptional matters. We study $G_2$ theories with\n$n_{\\bf…

2D Seiberg-like dualities for orthogonal gauge groups Open
We consider the analogue of Seiberg duality for two-dimensional $N=(2,2)$ gauge theory with orthogonal gauge groups and with fundamental chiral multiplets proposed by Hori. Following Hori, when we consider $O(N)$ gauge group as the (semi)-…

Elliptic genus of E-strings Open
We study a family of 2d N=(0,4) gauge theories which describes at low energy\nthe dynamics of E-strings, the M2-branes suspended between a pair of M5 and M9\nbranes. The gauge theory is engineered using a duality with type IIA theory,\nlea…

Aspects of String Dualities--Orientifolds, F-Theory and Super D-Branes & the M5-Brane Open
We probe string dualities by using the orientifold and F-theory, and by investigating world volume actions of super D-branes and super M-branes. We first study orientifolds in various dimensions. We construct orientifolds dual to M-theory …

6d strings from new chiral gauge theories Open
We study the 6d $\mathcal{N}=(1,0)$ superconformal field theory with smallest non-Higgsable gauge symmetry $SU(3)$. In particular, we propose new 2d gauge theory descriptions of its self-dual strings in the tensor branch. We use our gauge …

Factorization of the 3d superconformal index with an adjoint matter Open
We work out the factorization of the 3d superconformal index for N = 2 U(N-c) gauge theory with one adjoint chiral multiplet as well as N-f fundamental, N-a anti-fundamental chiral multiplets. Using the factorization, one can prove the Sei…

General instanton counting and 5d SCFT Open
Instanton partition functions of 5d N = 1 gauge theories are Witten indices for the ADHM gauged quantum mechanics with (0, 4) SUSY. We derive the integral contour prescriptions for these indices using the Jeffrey-Kirwan method, for gauge t…
