Microscopic and Macroscopic Behaviors of Palatini Modified Gravity Theories
Baojiu Li, David F. Mota, Douglas J. Shaw
We show that, within modified gravity, the non-linear nature of the field equations implies that the usual naive averaging procedure (replacing the microscopic energy-momentum by i…
Testing Alternative Theories of Dark Matter with the CMB
Baojiu Li, John D. Barrow, David F. Mota +1
We propose a method to study and constrain modified gravity theories for dark matter using CMB temperature anisotropies and polarization. We assume that the theories considered her…
Beyond the Chameleon Mechanism
David F. Mota, Douglas J. Shaw
As a result of non-linear self-interactions, in chameleon theories where the field couples to matter much more strongly than gravity does, the fifth force between two bodies with t…
Hidden in the Light: Magnetically Induced Afterglow from Trapped Chameleon Fields
Holger Gies, David F. Mota, Douglas J. Shaw
We propose an afterglow phenomenon as a unique trace of chameleon fields in optical experiments. The vacuum interaction of a laser pulse with a magnetic field can lead to a product…
Detecting Chameleons through Casimir Force Measurements
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +2
The best laboratory constraints on strongly coupled chameleon fields come not from tests of gravity per se but from precision measurements of the Casimir force. The chameleonic for…
Detecting a Lorentz-Violating Field in Cosmology
Baojiu Li, David F. Mota, John D. Barrow
We consider cosmology in the Einstein-aether theory (the generally covariant theory of gravitation coupled to a dynamical timelike Lorentz-violating vector field) with a linear aet…
