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…
Open-string T-duality and applications to non-geometric backgrounds
Fabrizio Cordonier-Tello, Dieter Lust, Erik Plauschinn
We revisit T-duality transformations for the open string via Buscher's procedure and work-out technical details which have been missing so far in the literature. We take into accou…
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…
Randall-Sundrum brane universe as a ground state for Chern-Simons gravity
Fabrizio Cordonier-Tello, Fernando Izaurieta, Patricio Mella +1
In stark contrast with the three-dimensional case, higher-dimensional Chern-Simons theories can have non-topological, propagating degrees of freedom. Finding those vacua that allow…
