Higher-order theories of gravity: diagnosis, extraction and reformulation via non-metric extra degrees of freedom
Alessio Belenchia, Marco Letizia, Stefano Liberati +1
Modifications of Einstein's theory of gravitation have been extensively considered in the past years, in connection to both cosmology and quantum gravity. Higher-curvature and high…
Tests of Quantum Gravity-Induced Non-Locality via Opto-mechanical Experiments
Alessio Belenchia, Dionigi M. T. Benincasa, Stefano Liberati +3
The nonrelativistic limit of nonlocal modifications to the Klein Gordon operator is studied, and the experimental possibilities of casting stringent constraints on the nonlocality…
Low energy signatures of nonlocal field theories
Alessio Belenchia, Dionigi M. T. Benincasa, Eduardo Martin-Martinez +1
The response of inertial particle detectors coupled to a scalar field satisfying nonlocal dynamics described by nonanalytic functions of the d'Alembertian operator is studie…
Lorentz violation naturalness revisited
Alessio Belenchia, Andrea Gambassi, Stefano Liberati
We revisit here the naturalness problem of Lorentz invariance violations on a simple toy model of a scalar field coupled to a fermion field via a Yukawa interaction. We first revie…
