Abstract The quantization of semiclassical strings in AdS spacetimes yields predictions for the strong-coupling behaviour of the scaling dimensions of the corresponding operators in the planar limit of the dual gauge theory. Finding non-planar correc

Abstract We compute the one-loop 2 → 2 scattering amplitude of massless scalars on the world volume of an infinite D = 11 supermembrane quantized in the static gauge. The resulting expression is manifestly finite and turns out to be much simpler th

Abstract We consider a 1 2 $$ \frac{1}{2} $$ -BPS solution for a D3 brane probe in AdS5 × S 5 that has world-volume geometry of AdS3 × S 1. It intersects the boundary over a surface that represents a dimension 2 defect in the boundary N $$ \mathcal

Abstract We consider type IIB string theory on an AdS 5 × S 5/ℤ2 orbifold background, which should be dual to 4d N $$ \mathcal{N} $$ = 2 superconformal SU(N) × SU(N) gauge theory with two bi-fundamental hypermultiplets. The correlator of two chir

Abstract We construct a family of type IIB string backgrounds that are deformations of AdS3 × S3 × T4 with a “squashed” AdS3 × S3 metric supported by a combination of NSNS and RR fluxes. They have global SU(1, 1) × SU(2) symmetry, regular cur

Abstract Motivated by a possibility of solving non-supersymmetric type 0 string theory in AdS 5 × S 5 background using integrability, we revisit the construction of type 0 string spectrum in some solvable examples of backgrounds with RR fluxes that

Abstract We consider a class of 2d σ-models on products of group spaces that provide new examples of a close connection between integrability and stability under the RG flow. We first study the integrable G × G model derived from the affine Gaudin

Abstract We consider several classes of σ-models (on groups and symmetric spaces, η-models, ⋋-models) with local couplings that may depend on the 2d coordinates, e.g. on time τ . We observe that (i) starting with a classically integrable 2d σ-m

Abstract Surface operators in the 6d (2,0) theory at large N have a holographic description in terms of M2 branes probing the AdS7 × S 4 M-theory background. The most symmetric, 1/2-BPS, operator is defined over a planar or spherical surface, and it
