Trapping cold atoms near carbon nanotubes: thermal spin flips and Casimir-Polder potential
arXiv:quant-ph/0703155 · doi:10.1103/PhysRevA.75.062905
Abstract
We investigate the possibility to trap ultracold atoms near the outside of a metallic carbon nanotube (CN) which we imagine to use as a miniaturized current-carrying wire. We calculate atomic spin flip lifetimes and compare the strength of the Casimir-Polder potential with the magnetic trapping potential. Our analysis indicates that the Casimir-Polder force is the dominant loss mechanism and we compute the minimum distance to the carbon nanotube at which an atom can be trapped.
