Abstract We consider the 𝒩 = (2, 2) AdS3/CFT2 dualities proposed by Eberhardt, where the bulk geometry is AdS3 × (S 3 × T 4)/ℤ k , and the CFT is a deformation of the symmetric orbifold of the supersymmetric sigma model T 4/ℤ k (with k = 2,

Abstract We consider N $$ \mathcal{N} $$ = (2, 2) AdS3/CFT2 dualities proposed in the large central charge limit (c → ∞) by Eberhardt. Here we propose the associated D1-D5 systems to be orbifolds of the standard N $$ \mathcal{N} $$ = (4, 4) syste

Abstract We present a prototype for Wilsonian analysis of asymptotics of supersymmetric partition functions of non-abelian gauge theories. Localization allows expressing such partition functions as an integral over a BPS moduli space. When the limit

Abstract We consider the S 3×S 1 superconformal index ℐ(τ) of 4d N $$ \mathcal{N} $$ = 1 gauge theories. The Hamiltonian index is defined in a standard manner as the Witten index with a chemical potential τ coupled to a combination of angular mo

Abstract We revisit the vacuum structure of the N $$ \mathcal{N} $$ = 1 Intriligator-Seiberg-Shenker model on ℝ3 × S 1. Guided by the Cardy-like asymptotics of its Romelsberger index, and building on earlier semi-classical results by Poppitz and

Abstract We study the Cardy-like asymptotics of the 4d N $$ \mathcal{N} $$ = 4 index and demonstrate the existence of partially deconfined phases where the asymptotic growth of the index is not as rapid as in the fully deconfined case. We then take t

Abstract We study the Casimir energy of bulk fields in AdS3 and its relation to subleading terms in the central charge of the dual CFT2. Computing both sides of the standard CFT2 relation E = −c/12 independently we show that this relation is not ne

Abstract Choi, Kim, Kim, and Nahmgoong have recently pioneered analyzing a Cardy-like limit of the superconformal index of the 4d N = 4 $$ \mathcal{N}=4 $$ theory with complexified fugacities which encodes the entropy of the dual supersymmetric AdS5

We consider the $S^3\times S^1$ superconformal index $\mathcal{I}(\tau)$ of 4d $\mathcal{N}=1$ gauge theories. The Hamiltonian index is defined in a standard manner as the Witten index with a chemical potential $\tau$ coupled to a combination of angu

We study the Cardy-like asymptotics of the 4d $\mathcal N=4$ index and demonstrate the existence of partially deconfined phases where the asymptotic growth of the index is not as rapid as in the fully deconfined case. We then take the large-$N$ limit
