The effect of spacetime curvature on photon motion may offer an opportunity to propose new tests on gravity theories.In this study,we investigate and focus on the massless(photon)particle motion around blackbounce gra...
A theory of Quantum Gravity based on Primordial Field Theory is applied to a fundamental particle, the neutron. The result is compared to the current quantum description of the neutron bouncing in a gravitational fiel...

Within the context of the Fermi-bounce curvaton mechanism,we analyze the one-loop radiative corrections to the four-fermion interaction,generated by the non-dynamical torsion field in the Einstein-Cartan-Holst-Sciama-...

We elaborate on a toy model of matter bounce, in which the matter content is constituted by two fermion species endowed with four fermion interaction terms. We describe the curvaton mechanism that is thus generated, a...
