Exact solutions of closed string theory [PDF]

, 1995
We review explicitly known exact $D=4$ solutions with Minkowski signature in closed bosonic string theory. Classical string solutions with space-time interpretation are represented by conformal sigma models.

Extreme dyonic black holes in string theory [PDF]

, 1996
Supersymmetric extreme dyonic black holes of toroidally compactified heterotic or type II string theory can be viewed as lower-dimensional images of solitonic strings wound around a compact dimension.

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.

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.

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.

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 ...

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.

Relaxation in Conformal Field Theory, Hawking-Page Transition, and Quasinormal/Normal Modes [PDF]

, 2002
We study the process of relaxation back to thermal equilibrium in $(1+1)$-dimensional conformal field theory at finite temperature. When the size of the system is much larger than the inverse temperature, perturbations decay exponentially with time.

Exact non-abelian duality [PDF]

, 1996
We investigate non-abelian gaugings of WZNW models. When the gauged group is semisimple we are able to present exact formulae for the dual conformal field theory, for all values of the level $k$.

ℤ2 boundary twist fields and the moduli space of D-branes

Journal of High Energy Physics, 2018
We revisit the boundary conformal field theory of twist fields. Based on the equivalence between twisted bosons on a circle and the orbifold theory at the critical radius, we provide a bosonized representation of boundary twist fields and thus a free ...
