Role of the remnant symmetries in gravitational theories based on absolute parallelism: a 2D standpoint

Franco Fiorini, Andronikos Paliathanasis

By using simplified 2D gravitational, non-local Lorentz invariant actions constructed upon the torsion tensor, we discuss the physical meaning of the remnant symmetries associated…

Exact results on analogue gravity in optical Plebanski-Tamm media

Franco Fiorini, Santiago M. Hernandez, Edith L. Losada

Exact results concerning ray-tracing methods in Plebanski-Tamm media are derived. In particular, Hamilton equations describing the propagation of quasi-plane wave electromagnetic f…

Matching tetrads in f(T) gravity

Franco Fiorini, Martín Onetto

The procedure underlying the matching of 1-form (tetrad) fields in theories possessing absolute parallelism -- f(T) gravity being within this category -- is addressed and exemplifi…

Regular black holes in three dimensions

Pablo Bueno, Pablo A. Cano, Javier Moreno +1

We find a plethora of new analytic black holes and globally regular horizonless spacetimes in three dimensions. The solutions involve a single real scalar field which always ad…
