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 ...

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.

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 ...

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.

String/Gauge Duality and Penrose Limit [PDF]
, 2003 Berenstein, Maldacena, and Nastase have recently discovered a particular limit of AdS/CFT correspondence where string theory in a plane wave background is dual to a sector of $mathcal N =4 SYM in a double scaling limit.

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.

Remarks on quiver gauge theories from open topological string theory [PDF]
, 2010 We study effective quiver gauge theories arising from a stack of D3-branes on certain Calabi-Yau singularities. Our point of view is a first principle approach via open topological string theory.

Ising model conformal boundary conditions from open string field theory
, 2014 Given a consistent choice of conformally invariant boundary conditions in a two dimensional conformal field theory, one can construct new consistent boundary conditions by deforming with a relevant boundary operator and flowing to the infrared, or by a marginal deformation.
