Luminal Propagation of Gravitational Waves in Scalar-tensor Theories: The Case for Torsion
José Barrientos, Fabrizio Cordonier-Tello, Cristóbal Corral +4
Scalar-tensor gravity theories with a nonminimal Gauss-Bonnet coupling typically lead to an anomalous propagation speed for gravitational waves, and have therefore been tightly con…
Wave Operators, Torsion, and Weitzenböck Identities
José Barrientos, Fernando Izaurieta, Eduardo Rodríguez +1
We offer a mathematical toolkit for the study of waves propagating on a background manifold with nonvanishing torsion. Examples include electromagnetic and gravitational waves on a…
Nonminimal couplings, gravitational waves, and torsion in Horndeski's theory
José Barrientos, Fabrizio Cordonier-Tello, Fernando Izaurieta +4
The Horndeski Lagrangian brings together all possible interactions between gravity and a scalar field that yield second-order field equations in four-dimensional spacetime. As orig…
