We present a pedagogical overview of flux compactifications in string theory, from the basic
ideas to the most recent developments. We concentrate on closed-string fluxes in type-II …

In this review article, we describe the role of holography in deciphering the physics of dense
QCD matter, relevant for the description of compact stars and their binary mergers. We …

A bstract Geometric engineering is a collection of tools developed to establish dictionaries
between local singularities in string theory and (supersymmetric) quantum fields. Extended …

We find the gravity dual of a marginal deformation of Script N= 4 super Yang Mills, and
discuss some of its properties. This deformation is intimately connected with an SL (2, Bbb …

We describe a technique which enables one to quickly compute an infinite number of toric
geometries and their dual quiver gauge theories. The central object in this construction is …

We develop a systematic and efficient method of counting single-trace and multi-trace BPS
operators with two supercharges, for world-volume gauge theories of N D-brane probes for …

We study a variational problem whose critical point determines the Reeb vector field for a
Sasaki–Einstein manifold. This extends our previous work on Sasakian geometry by lifting …

Abstract Recently Lunin and Maldacena used an SL (3, Bbb R) transformation of the AdS 5×
S 5 background to generate a supergravity solution dual to a so-called β-deformation of …

A bstract In this paper we present three new families of smooth Type II string theory
backgrounds. These are dual to supersymmetry-preserving deformations of 4d SCFTs. The …

We discuss the theory of equivariant localization focussing on applications relevant for
holography. We consider geometries comprising compact and non-compact toric orbifolds …
