Mimetic Einstein-Cartan-Kibble-Sciama (ECKS) gravity
F. Izaurieta, P. Medina, N. Merino +2
In this paper, we formulate the Mimetic theory of gravity in first-order formalism for differential forms, i.e., the mimetic version of Einstein-Cartan-Kibble-Sciama (ECKS) gravity…
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…
Non-minimally coupled scalar field cosmology with torsion
Antonella Cid, Fernando Izaurieta, Genly Leon +2
In this work we present a generalized Brans-Dicke lagrangian including a non-minimally coupled Gauss-Bonnet term without imposing the vanishing torsion condition. In the resulting…
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…
