Worldsheet string theory on
Lorenz Eberhardt, Matthias R. Gaberdiel, Sameer Murthy +1
The RNS formalism describing string theory on supported by pure NS-NS flux is in principle straightforward to write down. On…
Classification of c=1 CFTs
Lorenz Eberhardt, Nat Levine
We completely classify unitary 2d CFTs with central charge and discrete spectrum. We confirm the folklore that the only such theories are the compact free boson, its $\mathbb…
CFT characters from localization
Lorenz Eberhardt, Duarte Fragoso, Hessel Posthuma
We explain a general procedure to compute characters of chiral algebras of 2d (S)CFTs geometrically from their coadjoint orbits, in analogy with the coadjoint orbit method for fini…
The Runkel-Watts string
Mattia Biancotto, Lorenz Eberhardt, Victor A. Rodriguez +1
We introduce and solve a new family of two-dimensional string theories obtained by coupling Liouville CFT to the generalized Runkel-Watts CFT. By taking an appropriate limit of the…
What makes spacetime spin in string theory?
Matilda Delgado, Lorenz Eberhardt, Marija Tomašević
Type II string theory in the absence of orientifolds requires the target spacetime to admit a spin structure. We show that this familiar requirement arises directly from the co…
strings as a matrix integral
Scott Collier, Lorenz Eberhardt, Victor A. Rodriguez
We study the perturbative -matrix of the string and show that it admits a description in terms of a double-scaled (0+0)-dimensional matrix integral based on the spectral c…
The Super Virasoro Minimal String from 3d Supergravity
Lorenz Eberhardt
The super Virasoro minimal string is defined by coupling spacelike and timelike super Liouville theories on the worldsheet. There are four different theories 0A and 0B…
Precision asymptotics of string amplitudes
Marco Maria Baccianti, Lorenz Eberhardt, Sebastian Mizera
Recent work revealed a tension between the Gross-Mende analysis of the high-energy fixed-angle behavior of string amplitudes and the explicit numerical data. Motivated by this puzz…
A universal sum over topologies in 3d gravity
Alexandre Belin, Scott Collier, Lorenz Eberhardt +2
We explore the sum over topologies in AdS quantum gravity and its relationship with the statistical interpretation of the boundary theory. We formulate a statistical version of…
