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…
Upper bound on the Abelian gauge coupling from asymptotic safety
Astrid Eichhorn, Fleur Versteegen
We explore the impact of asymptotically safe quantum gravity on the Abelian gauge coupling in a model including a charged scalar, confirming indications that asymptotically safe qu…
Quantum Gravity signatures in the Unruh effect
Natalia Alkofer, Giulio D'Odorico, Frank Saueressig +1
We study quantum gravity signatures emerging from phenomenologically motivated multiscale models, spectral actions, and Causal Set Theory within the detector approach to the Unruh…
First- and second-order error estimates in Monte Carlo integration
R. Bakx, R. H. P. Kleiss, F. Versteegen
In Monte Carlo integration an accurate and reliable determination of the numerical intregration error is essential. We point out the need for an independent estimate of the error o…
