Causal Set theory, non-locality and phenomenology
Alessio Belenchia
This proceeding is based on a talk prepared for the XIV Marcel Grossmann meeting. We review some results on causal set inspired non-local theories as well as work in progress conce…
Tests of Quantum Gravity induced non-locality via opto-mechanical quantum oscillators
Alessio Belenchia, Dionigi M. T. Benincasa, Stefano Liberati +3
Several quantum gravity scenarios lead to physics below the Planck scale characterised by nonlocal, Lorentz invariant equations of motion. We show that such non-local effective fie…
Universal behaviour of generalized Causal set d'Alembertians in curved spacetime
Alessio Belenchia
Causal set non-local wave operators allow both for the definition of an action for Causal set theory and the study of deviations from local physics that may have interesting phenom…
The continuum limit of a 4-dimensional causal set scalar d'Alembertian
Alessio Belenchia, Dionigi M. T. Benincasa, Fay Dowker
The continuum limit of a 4-dimensional, discrete d'Alembertian operator for scalar fields on causal sets is studied. The continuum limit of the mean of this operator in the Poisson…
Spectral Dimension from Nonlocal Dynamics on Causal Sets
Alessio Belenchia, Dionigi M. T. Benincasa, Antonino Marciano +1
We investigate the spectral dimension obtained from non-local continuum d'Alembertians derived from causal sets. We find a universal dimensional reduction to 2 dimensions, in all d…
