Journal of High Energy Physics, 2022 Compactification of M-theory and of IIB string theory on threefold canonical singularities gives rise to superconformal field theories (SCFTs) in 5d and 4d, respectively.

Locality and causality properties of light cone string field theory [PDF]
, 2004 The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

Gauge invariant cosmological perturbations for the nonminimally coupled inflaton field [PDF]
, 2010 We construct the gauge invariant free action for cosmological perturbations for the nonminimally coupled inflaton field in the Jordan frame. For this the phase space formalism is used, which keeps track of all the dynamical and constraint fields.

Long strings and chiral primaries in the hybrid formalism
Journal of High Energy Physics, 2019 We revisit two related phenomena in AdS3 string theory backgrounds. At pure NS-NS flux, the spectrum contains a continuum of long strings which can escape to the boundary of AdS3 at a finite cost of energy.

One loop phenomenology of type II string theory: intersecting d-branes and noncommutativity [PDF]
, 2007 We examine one loop amplitudes for open and closed strings in certain D-brane configurations, and investigate the consequences for phenomenology. Initially we consider open strings at D6-brane intersections.

On the classification of 5d SCFTs
Journal of High Energy Physics, 2020 We determine all 5d SCFTs upto rank three by studying RG flows of 5d KK theories. Our analysis reveals the existence of new rank one and rank two 5d SCFTs not captured by previous classifications.

Aspects of plane waves and Taub-NUT as exact string theory solutions [PDF]
, 2004 This thesis is a study of some aspects of string theory solutions that are exact in the inverse string tension ɑ', and thus are valid beyond the low-energy limit.

Journal of High Energy Physics, 2019 Supersymmetric theories with the same bosonic content but different fermions, aka twins, were thought to exist only for supergravity. Here we show that pairs of super conformal field theories, for example exotic N $$ \mathcal{N} $$ = 3 and N $$ \mathcal ...

A large-D Weyl invariant string model in anti-de sitter space [PDF]
, 2002 In this thesis we present a novel scheme for calculating the bosonic string partition function on certain curved backgrounds related to Anti-de Sitter [AdS] space.

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]
, 2010 The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...
