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…
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…
