Published in 2019 at "Classical and Quantum Gravity"

DOI: 10.1088/1361-6382/ab0a40

Abstract: Recently, a proposal has been made to figure out the expected discrete nature of spacetime at the smallest scales in terms of atoms of spacetime, capturing their effects through a scalar $\rho$, related to their… read more here.

Published in 2020 at "Physical Review D"

DOI: 10.1103/physrevd.102.124057

Abstract: We consider spacetime endowed with a zero point length, i.e. with an effective metric structure which allows for a (quantum-mechanically arising) finite distance $L_0$ between events in the limit of their coincidence. Restricting attention to… read more here.
