Supertranslations and Superrotations at the Black Hole Horizon
Laura Donnay, Gaston Giribet, Hernan A. Gonzalez +1
We show that the asymptotic symmetries close to nonextremal black hole horizons are generated by an extension of supertranslations. This group is generated by a semidirect sum of V…
Dark energy and Equivalence Principle constraints from astrophysical tests of the stability of the fine-structure constant
C. J. A. P. Martins, A. M. M. Pinho, R. F. C. Alves +3
Astrophysical tests of the stability of fundamental couplings, such as the fine-structure constant , are becoming an increasingly powerful probe of new physics. Here we discuss…
Cosmological Kinetic Mixing
Ashok Das, Jorge Gamboa, Miguel Pino
In this paper we generalize the kinetic mixing idea to time reparametrization invariant theories, namely, relativistic point particles and cosmology in order to obtain new insights…
