Black-hole evaporation from the semiclassical Einstein equations in 3+1 dimensions

Adrián del Río, F. Javier Marañón-González

The paper presents an analytical solution of the semiclassical Einstein equations describing the backreacted geometry of an evaporating Schwarzschild black hole in four dimensions,…

Intrinsic handedness in O1-O4a black-hole mergers: probing orbital precession, remnant retention in dense environments and cosmological mirror asymmetry

Juan Calderón Bustillo, Adrián del Rio, Nicolás Sanchis-Gual +1

Precessing binary black-holes generically produce an imbalance of right- and left- handed gravitational waves, reflecting the breaking of mirror symmetry by the merger dynamics. We…

Asymmetric excitation of left- vs right-handed photons in accelerating waveguides

Adrian del Rio

The electromagnetic duality symmetry of Maxwell's equations in vacuum implies that the circular polarization of classical electromagnetic waves is conserved. In quantum field t…

Duality Symmetry and Anomaly for Gravitational Waves in Curved Spacetime

Adrian del Rio, Javier Olmedo, António Torres Manso

The vacuum Einstein equations admit a formulation closely analogous to the source-free Maxwell theory. In particular, the linearized equations exhibit an electric-magnetic duality…

Photon helicity asymmetry and duality anomaly in rotating waveguides

Adrian del Rio

In quantum field theory, photon pairs can be excited out of the vacuum under the influence of dynamical gravitational fields. If the classical electromagnetic duality symmetry held…

Cosmological mirror symmetry and gravitational-wave helicity

Juan Calderón-Bustillo, Adrian del Rio, Samson H. W. Leong +1

Our current understanding of the Universe relies on the hypothesis that, when observed at sufficiently large scales, it looks statistically identical regardless of location or dire…
