Thermality of the zero-point length and gravitational selfduality
P. Fernandez de Cordoba, J. M. Isidro, Rudranil Roy
It has been argued that the existence of a zero-point length is the hallmark of quantum gravity. In this letter we suggest a thermal mechanism whereby this quantum of length arises…

Spacetime metric from quantum-gravity corrected Feynman propagators
P. Fernandez de Cordoba, J. M. Isidro, Rudranil Roy
Differentiation of the scalar Feynman propagator with respect to the spacetime coordinates yields the metric on the background spacetime that the scalar particle propagates in. Now…
