Abstract

The experiment aims at coupling the thermal oscillations of a nanomechanical resonator to the spin of a nearby Bose-Einstein condensate via a magnetic interaction. The coupling is mediated by a small island of ferromagnetic material on the cantilever. In this way, the resonator motion causes an oscillating magnetic field that can drive atomic spin-flip transitions. If the eigenfrequency of the beam is resonant with transitions to untrapped magnetic sublevels, observable trap loss occurs.
