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

Affine Connections and Topological Conformal Field Theories on Higher-Genus Riemann Surfaces. II: Bosonic Strings and Related Models [PDF]
Progress of Theoretical Physics, 1993 The topological conformal algebra for the models of bosonic string type is considered on an arbitrary higher-genus Riemann surface M. Associated with the U(1) anomaly the affine connection is automatically introduced into the algebra. The affine connection always appears in the form of covariant derivatives, so that it guarantees coordinate ...

The DOZZ formula from the path integral
Journal of High Energy Physics, 2018 We present a rigorous proof of the Dorn, Otto, Zamolodchikov, Zamolodchikov formula (the DOZZ formula) for the 3 point structure constants of Liouville Conformal Field Theory (LCFT) starting from a rigorous probabilistic construction of the functional ...

Space-time CFTs from the Riemann sphere
Journal of High Energy Physics, 2017 We consider two-dimensional chiral, first-order conformal field theories governing maps from the Riemann sphere to the projective light cone inside Minkowski space — the natural setting for describing conformal field theories in two fewer dimensions ...

Black hole microstates from the worldsheet
Journal of High Energy Physics, 2021 Recently an exact worldsheet description of strings propagating in certain black hole microstate geometries was constructed in terms of null-gauged WZW models.

A puncture in the Euclidean black hole
Journal of High Energy Physics, 2022 We consider the backreaction of the winding condensate on the cigar background. We focus on the case of the SL(2, ℝ) k /U(1) cigar associated with, e.g., the near-horizon limit of k NS5 black-branes.

Stringy information and black holes
Journal of High Energy Physics, 2020 We show that in string theory, due to non-perturbative effects, there are cases in which two states that semi-classically are completely different, are in fact the same.

Normalization of ZZ instanton amplitudes in minimal string theory
Journal of High Energy Physics, 2022 We use insights from string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane.
