T-duality invariant approaches to string theory [PDF]
, 2010 PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.

On black holes in string theory [PDF]
, 2011 PhDThis thesis investigates black holes in string theory through string amplitudes and through gauge-gravity duality. The research presented in this thesis supports the claim that string theory is capable of a consistent quantum-mechanical description

Fundamental membranes and the string dilaton
Journal of High Energy Physics, 2022 We study the quantization of the bosonic sector of supermembrane theory in double dimensional reduction, in order to extract the dependence of the resulting world-sheet action on the string dilaton (which cannot be obtained from a purely kinematic ...

Cutkosky rules and unitarity (violation) in D-instanton amplitudes
Journal of High Energy Physics, 2021 In perturbative amplitudes in quantum field theory and string field theory, Cutkosky rule expresses the anti-hermitian part of a Feynman diagram in terms of sum over all its cut diagrams, and this in turn is used to prove unitarity of the theory.

The asymptotic Weak Gravity Conjecture for open strings
Journal of High Energy Physics, 2022 We investigate the asymptotic Tower Weak Gravity Conjecture in weak coupling limits of open string theories with minimal supersymmetry in four dimensions, focusing for definiteness on gauge theories realized on 7-branes in F-theory.

STOKES PHENOMENA AND QUANTUM INTEGRABILITY IN NON-CRITICAL STRING/M THEORY [PDF]
International Journal of Modern Physics: Conference Series, 2012 Non-critical string/M theory is a solvable model which has been studied to reveal various non-perturbative aspects of string theory with providing new key concepts to the next developments of string theory. Here we show some recent progress in study of Stokes phenomenon in non-critical string theory of the multi-cut two-matrix models.

Cosmic necklaces in string theory and field theory [PDF]
, 2010 PhDIn this thesis we investigate astrophysical phenomena which arise in models with compact extra dimensions, focussing on the cosmological consequences of strings which wrap cycles in the internal space. Embedding our strings in the Klebanov-Strassler

Finiteness of entanglement entropy in collective field theory
Journal of High Energy Physics, 2022 We explore the question of finiteness of the entanglement entropy in gravitational theories whose emergent space is the target space of a holographic dual.
