Space-like Singularities of General Relativity: A Phantom menace?
Abhay Ashtekar, Adrián del Río, Marc Schneider
The big bang and the Schwarzschild singularities are space-like. They are generally regarded as the "final frontiers" at which space-time ends and general relativity breaks down. W…

Electromagnetic duality anomaly in curved spacetimes
I. Agullo, A. del Rio, J. Navarro-Salas
The source-free Maxwell action is invariant under electric-magnetic duality rotations in arbitrary spacetimes. This leads to a conserved classical Noether charge. We show that this…

Equivalence of Adiabatic and DeWitt-Schwinger renormalization schemes
Adrian del Rio, Jose Navarro-Salas
We prove that adiabatic regularization and DeWitt-Schwinger point-splitting provide the same result for the renormalized expectation values of the stress-energy tensor for spin-$1/…
