On the mass spectrum of Viel-dreibein gravity
Eloy Ayón-Beato, Elizabeth Rodr\'ıguez Querts
We study the AdS-wave configurations of Viel-dreibein gravity, a three-dimensional theory of interacting spin-2 fields, as a pretext to characterize the mass spectrum of this m…
The dyonic Kerr-Schild ansatz
Eloy Ayón-Beato, Daniel Flores-Alfonso, Mokhtar Hassaine +1
We develop a geometric extension of the Kerr-Schild ansatz that incorporates both electric and magnetic sectors of the Maxwell field in a unified framework, without resorting to du…
Ultrarelativistic limit of the Kerr theorem
Eloy Ayón-Beato, Daniel Flores-Alfonso, Mokhtar Hassaine
The original Kerr theorem provides the foundation for Kerr-Schild transformations by classifying all shear-free and geodesic null congruences in flat spacetime; the key ingredient…
Non-Noetherian conformal Cheshire effect
Eloy Ayón-Beato, Mokhtar Hassaine, Pedro A. Sánchez
The gravitational Cheshire effect refers to the possibility of turning off the gravitational field while still leaving an imprint of the nonminimal coupling of matter to gravity. T…
Nonlinearly charging the conformally dressed black holes preserving duality and conformal invariance
Eloy Ayón-Beato, Daniel Flores-Alfonso, Mokhtar Hassaine
We start this paper by concisely rederiving ModMax, which is nothing but the unique nonlinear extension of Maxwell's equations preserving conformal and duality invariance. The meri…
Uniqueness of the Jackiw non-Noetherian conformal scalar field
Eloy Ayón-Beato, Mokhtar Hassaine
Jackiw was undoubtedly the first to exhibit an example of a scalar field action which is not conformally invariant whereas its equation of motion is. This feature has recently been…
