Teleparallel Jackiw-Teitelboim gravity
Christian G. Boehmer, Rafael Ferraro, Franco Fiorini
We introduce a new class of two dimensional gravity models using ideas motivated by the Teleparallel Equivalent of General Relativity. This leads to a rather natural formulation of…
Local symmetries in -like models: lessons from 2D
Franco Fiorini
The comprehension of the intricate structure associated to the local symmetries encoded in the tetrad field, as well as its physical meaning, is perhaps the most important unsolved…
Chronology protection in gravity: the case of Gott's pair of moving cosmic strings
Franco Fiorini
As a consequence of the spacetime structure, defined by the tetrad field instead of the metric tensor alone, gravity seems to harbor its own chronology protection agency. Wh…
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…
