Off-shell Partition Functions in 3d Gravity
Lorenz Eberhardt
We explore three-dimensional gravity with negative cosmological constant via canonical quantization. We focus on chiral gravity which is related to a single copy of $\mathrm{PSL}(2…
On Unitarity of Tree-Level String Amplitudes
Nima Arkani-Hamed, Lorenz Eberhardt, Yu-tin Huang +1
Four-particle tree-level scattering amplitudes in string theory are magically consistent with unitarity, reflected in the non-trivial fact that beneath the critical dimension, the…
String correlators on : Four-point functions
Andrea Dei, Lorenz Eberhardt
We propose a closed-form formula for genus 0 four-point functions in string theory with pure NS-NS flux including arbitrary amounts of spectral flow. Our formula pas…
String correlators on : Three-point functions
Andrea Dei, Lorenz Eberhardt
We revisit the computation of string worldsheet correlators on Euclidean with pure NS-NS background. We compute correlation functions with insertions of spectrally f…
The Disk Partition Function in String Theory
Lorenz Eberhardt, Sridip Pal
We investigate the disk partition function for the open string. This is a subtle problem because of the presence of a residual gauge group on the world…
Partition functions of the tensionless string
Lorenz Eberhardt
We consider string theory on in the tensionless limit, with one unit of NS-NS flux. This theory is conjectured to describe the…
