Cold Atoms On Nanostructures — •Carsten Weiß^1,2, Reinhold Walser¹, Wolfgang P. Schleich¹, and József Fortágh² — ¹Institut für Quantenphysik, Universität Ulm — ²Physikalisches Institut, Universität Tübingen

A single-walled carbon nanotube (SWCNT) mounted on a lithographically fabricated chip defines a nearly perfect mechanical nano-oscillator. At common temperatures of a cryogenically cooled chip surface it performs large classical oscillations. By exposing it to ultra-cold alkali atoms we want to study the elastic and inelastic scattering by the SWCNT. In particular, we will present simulations for the interaction between a nanotube and a polarizable ⁸⁷Rb atom.
