Asymptotic safety, string theory and the weak gravity conjecture
Senarath de Alwis, Astrid Eichhorn, Aaron Held +3
We propose a scenario with string theory in the deep ultraviolet, an intermediate asymptotically safe scaling regime for gravity and matter, and the Standard Model in the infrared.…

Spectral dimension on spatial hypersurfaces in causal set quantum gravity
Astrid Eichhorn, Sumati Surya, Fleur Versteegen
An important probe of quantum geometry is its spectral dimension, defined via a spatial diffusion process. In this work we study the spectral dimension of a ``spatial hypersurface'…

Induced Spatial Geometry from Causal Structure
Astrid Eichhorn, Sumati Surya, Fleur Versteegen
Motivated by the Hawking-King-McCarthy-Malament (HKMM) theorem and the associated reconstruction of spacetime geometry from its causal structure and local volume elemen…
