Absence of covariant singularities in pure gravity
Roberto Casadio, Alexander Kamenshchik, Iberê Kuntz
The assumptions of the Hawking-Penrose singularity theorem are not covariant under field redefinitions. Thus we propose to study singularities in field space, where the spacetime m…

Revisiting the minimum length in the Schwinger-Keldysh formalism
Roberto Casadio, Iberê Kuntz
The existence of a minimum length in quantum gravity is investigated by computing the in-in expectation value of the proper distance in the Schwinger-Keldysh formalism. No minimum…

Bootstrapped Newtonian quantum gravity
Roberto Casadio, Iberê Kuntz
We compute quantum corrections for the gravitational potential obtained by including a derivative self-coupling in its classical dynamics as a toy model for analysing quantum gravi…
