Measurement of the Casimir-Polder force through center-of-mass oscillations of a Bose-Einstein condensate
Year: 2005
Type: article
Abstract: We have performed a measurement of the Casimir-Polder force using a magnetically trapped $^{87}\mathrm{Rb}$ Bose-Einstein condensate. By detecting perturbations of the frequency of center-of-mass oscillations of the condensate perpendicular to the surface, we are able to detect this force at a distance $\ensuremath{\sim}5\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$, significantly farther than has been previously achieved, and at a precision approaching that needed to detect the modification due to thermal radiation. Additionally, this technique provides a limit for the presence of non-Newtonian gravity forces in the $\ensuremath{\sim}1\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$ range.
