Detecting Dark Domain Walls
Kate Clements, Benjamin Elder, Lucia Hackermueller +2
Light scalar fields, with double well potentials and direct matter couplings, undergo density driven phase transitions, leading to the formation of domain walls. Such theories coul…
Constraining the chameleon-photon coupling with atomic spectroscopy
Benjamin Elder, Jeremy Sakstein
We compute bounds from atomic spectroscopy on chameleon fields that couple to the photon. Chameleons are a wide class of scalar field models that generically lead to screened fifth…
Casimir Tests of Scalar-Tensor Theories
Philippe Brax, Anne-Christine Davis, Benjamin Elder
We compute bounds and forecasts on screened modified gravity theories, specialising to the chameleon model in Casimir force experiments. In particular, we investigate the classical…
Mapping the Weak-Field Limit of Scalar-Gauss-Bonnet Gravity
Benjamin Elder, Jeremy Sakstein
We derive the weak field limit of scalar-Gauss-Bonnet theory and place novel bounds on the parameter space using terrestrial and space-based experiments. In order to analyze the th…
Hide and Seek: Screened Scalar Fields in Hydrogen and Muonium
Philippe Brax, Anne-Christine Davis, Benjamin Elder
We compute bounds on screened scalar field theories from hydrogen-like systems. New light scalar fields generically have a direct coupling to matter. Such a coupling is strongly co…
Testing Screened Modified Gravity
Philippe Brax, Santiago Casas, Harry Desmond +1
Long range scalar fields with a coupling to matter appear to violate known bounds on gravitation in the solar system and the laboratory. This is evaded thanks to screening mechanis…
