Notes on crossing transformations of Virasoro conformal blocks
Lorenz Eberhardt
We carefully bootstrap the crossing kernels of Virasoro conformal blocks from first principles. Our approach emphasizes the Hilbert space structure of the space of Virasoro conform…
The Virasoro Minimal String
Scott Collier, Lorenz Eberhardt, Beatrix Mühlmann +1
We introduce a critical string theory in two dimensions and demonstrate that this theory, viewed as two-dimensional quantum gravity on the worldsheet, is equivalent to a double-sca…
Holographic Weyl anomaly in string theory
Lorenz Eberhardt, Sridip Pal
We compute the worldsheet sphere partition function of string theory on global AdS with pure NS-NS flux. Because of an unfixed Möbius symmetry on the worldsheet, there is a can…
2D dilaton gravity and the Weil-Petersson volumes with conical defects
Lorenz Eberhardt, Gustavo J. Turiaci
We derive the Weil-Petersson measure on the moduli space of hyperbolic surfaces with defects of arbitrary opening angles and use this to compute its volume. We conjecture a matrix…
Solving 3d Gravity with Virasoro TQFT
Scott Collier, Lorenz Eberhardt, Mengyang Zhang
We propose a precise reformulation of 3d quantum gravity with negative cosmological constant in terms of a topological quantum field theory based on the quantization of the Teichmü…
Evaluating one-loop string amplitudes
Lorenz Eberhardt, Sebastian Mizera
We evaluate one-loop open-string amplitudes at finite for the first time. Our method involves a deformation of the integration contour over the modular parameter to a frac…
