Abstract
Pulses of light can be used to transfer momentum and energy to atoms.
Through appropriate tailoring of the pulses, a sequence of operations
can be used to create an analogue of an optical interferometer -
interchanging the roles of light and matter. First demonstrated
roughly 30 years ago, atom interferometry has since been used in a
variety of fundamental physics applications and, over the last
decade, has seen significant efforts in translation towards practical
applications. In Birmingham, we have been active in pursuing the
first field demonstrations of gravity gradiometers using atom
interferometry, and now, within the AION consortium, we are
investigating how this technique could be applied to study of dark
matter and gravitational waves.
