CMB Anisotropies and Inflation from Non-Standard Spinors
Christian G. Boehmer, David F. Mota
The apparent alignment of the cosmic microwave background multipoles on large scales challenges the standard cosmological model. Scalar field inflation is isotropic and cannot acco…
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…
Constraining Dark Energy Anisotropic Stress
D. F. Mota, J. R. Kristiansen, T. Koivisto +1
We investigate the possibility of using cosmological observations to probe and constrain an imperfect dark energy fluid. We consider a general parameterization of the dark energy c…
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…
Spinflation
Damien A. Easson, Ruth Gregory, David F. Mota +2
We study the cosmological implications of including angular motion in the DBI brane inflation scenario. The non-canonical kinetic terms of the Dirac-Born-Infeld action give an inte…
