Comment on "Interaction of a Bose-Einstein condensate with a gravitational wave"

Richard Howl, Dennis Rätzel, Ivette Fuentes

A gravitational-wave (GW) detector that utilizes the phononic excitations of a Bose-Einstein condensate (BEC) has recently been proposed [NJP 16, 085003 (2014)]. A subsequent and i…
