Journal ArticleDOI
Laboratory Tests of the Galileon
TL;DR: In this article, the authors describe how laboratory measurements of the Casimir effect and possible deviations from Newtonian gravity can be used to search for Galileon scalar fields, which are used to bound a previously unconstrained combination of Galileon parameters.
Journal ArticleDOI
Acoustic Rabi oscillations between gravitational quantum states and impact on symmetron dark energy
G. Cronenberg,Philippe Brax,Hanno Filter,Peter Geltenbort,Tobias Jenke,Guillaume Pignol,Mario Pitschmann,Martin Thalhammer,Hartmut Abele +8 more
TL;DR: In this article, a spectroscopic approach based on the Rabi resonance method was proposed to exclude the symmetron as the origin of Dark Energy for a large volume of the three-dimensional parameter space.
Journal ArticleDOI
Cosmological Tests of the Disformal Coupling to Radiation
TL;DR: In this paper, it was shown that light scalar fields can naturally couple disformally to Standard Model fields without giving rise to the unacceptably large fifth forces usually associated with light scalars.
Journal ArticleDOI
Acoustic Rabi oscillations between gravitational quantum states and impact on symmetron dark energy
G. Cronenberg,Philippe Brax,Hanno Filter,Peter Geltenbort,Tobias Jenke,Guillaume Pignol,Mario Pitschmann,Martin Thalhammer,Hartmut Abele +8 more
TL;DR: In this article, a spectroscopic approach based on the Rabi resonance method is used to probe the quantum states of ultracold neutrons and thus their interaction with the gravitational potential of the Earth.
Journal ArticleDOI
The speed of Galileon gravity
TL;DR: In this article, the authors analyzed the speed of gravitational waves in coupled Galileon models with an equation of state ωphgr=−1 now and a ghost-free Minkowski limit.
