Testing mirror symmetry in the Universe with LIGO-Virgo black-hole mergers
Juan Calderón Bustillo, Adrian del Rio, Nicolas Sanchis-Gual +2
Certain precessing black-hole mergers produce gravitational waves with net circular polarization, understood as an imbalance between right- and left-handed amplitudes. According to…
Electrically charged black hole solutions in semiclassical gravity and dynamics of linear perturbations
Adrián del Río, Evelyn-Andreea Ester
We explore quantum corrections of electrically charged black holes subject to vacuum polarization effects of fermion fields in QED. Solving this problem exactly is challenging so w…
Chiral fermion anomaly as a memory effect
Adrián del Río, Ivan Agullo
We study the non-conservation of the chiral charge of Dirac fields between past and future null infinity due to the Adler-Bell-Jackiw chiral anomaly. In previous investigations \ci…
Precessing binary black holes as engines of electromagnetic helicity
Nicolas Sanchis-Gual, Adrian del Rio
We show that binary black hole mergers with precessing evolution can potentially excite photons from the quantum vacuum in such a way that total helicity is not preserved in the pr…
Quantum corrections to the Schwarzschild metric from vacuum polarization
Pau Beltrán-Palau, Adrián del Río, José Navarro-Salas
We explore static and spherically symmetric solutions of the 4-dimensional semiclassical Einstein's equations using the quantum vacuum polarization of a conformal field as a source…
Absorption spectroscopy of quantum black holes with gravitational waves
Ivan Agullo, Vitor Cardoso, Adrián del Rio +2
The observation of electromagnetic radiation emitted or absorbed by matter was instrumental in revealing the quantum properties of atoms and molecules in the early XX century, and…
Spontaneous creation of circularly polarized photons in chiral astrophysical systems
Adrian del Rio, Nicolas Sanchis-Gual, Vassilios Mewes +3
This work establishes a relation between chiral anomalies in curved spacetimes and the radiative content of the gravitational field. In particular, we show that a flux of circularl…
Adiabatic regularization with a Yukawa interaction
A. del Rio, A. Ferreiro, J. Navarro-Salas +1
We extend the adiabatic regularization method for an expanding universe to include the Yukawa interaction between quantized Dirac fermions and a homogeneous background scalar field…
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/…
Renormalized stress-energy tensor for spin-1/2 fields in expanding universes
Adrian del Rio, Jose Navarro-Salas, Francisco Torrenti
We provide an explicit expression for the renormalized expectation value of the stress-energy tensor of a spin- field in a spatially flat FLRW universe. Its computation is bas…
Spacetime correlators of perturbations in slow-roll de Sitter inflation
Adrian del Rio, Jose Navarro-Salas
Two-point correlators and self-correlators of primordial perturbations in quasi-de Sitter spacetime backgrounds are considered. For large separations two-point correlators exhibit…
