We study cold atoms scattering from static and vibrating nanotubes. We find the scattering potential calculations for dielectric tubes can be greatly simplified with a modified pairwise summation approach. Quantum reflection of atoms from a nanotube is shown to become important if a Bose-Einstein condensate is used. Non-trivial absorption of atoms by nanotubes, as seen in experiments, is explained by inter-atomic interactions and quantum pressure. Natural nanotube vibrations do not significantly reduce condensate fractions, but lower frequency oscillations can dramatically heat the cloud.
