Shining Light on Dark Energy and Modifications of Gravity [PDF]
Clare BurrageMany theories of dark energy and modified gravity give rise to scalar fields that couple derivatively to the energy momentum tensor of matter. This is known as disformal coupling. I will show that laboratory searches for axions are ideally suited to search for and constrain disformal scalar fields.View original: http://arxiv.org/abs/1301.1603
