Cold atoms on nanostructures -- dynamics of a damped nanotube — •Carsten Weiß^1,2, József Fortágh², Wolfgang P. Schleich¹, and Reinhold Walser¹ — ¹Institut für Quantenphysik, Universität Ulm — ²Physikalisches Institut, Universität Tübingen

A single-wall carbon nanotube mounted on a lithographically fabricated chip defines an almost perfect mechanical nano-oscillator. Exposing it to an ultracold beam of rubidium atoms allows us to study inelastic scattering processes and damping mechanisms. In particular, we present a master equation for a damped carbon nanotube embedded in a beam of ultracold atoms.
