Probing cosmological singularities with quantum fields: Open and closed FLRW universes
Abhay Ashtekar, Adrián del Río
It was recently pointed out that linear quantum fields can be meaningfully propagated across the big bang (and the big crunch) singularities of spatially flat Friedmann…
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…
Chiral anomalies induced by gravitational waves
Adrian del Rio
Chiral symmetries in field theory are typically affected by an anomaly in the quantum theory. This anomaly emerges when one introduces an interaction with a Yang-Mills or gravitati…
Note on the pragmatic mode-sum regularization method: translational-splitting in a cosmological background
Pau Beltrán-Palau, Adrián del Río, Sergi Nadal-Gisbert +1
The point-splitting renormalization method offers a prescription to calculate finite expectation values of quadratic operators constructed from quantum fields in a general curved s…
Distinguishing black holes from horizonless objects through the excitation of resonances during inspiral
Vitor Cardoso, Adrian del Rio, Masashi Kimura
How well is the vacuum Kerr geometry a good description of the dark, compact objects in our universe? Precision measurements of accreting matter in the deep infrared and gravitatio…
