Msc Thesis title: Spin flip rate and heating of cold atoms trapped by a superconductor chip with a single vortex
abstract: We study trapping of a cold atom by a single vortex line in a superconducting chip. In particular we evaluate the spin flip rate due to the vortex fluctuations. We derive the boundary condition for a general shape vortex in an extreme type II superconductor. We find that there is a special spin orientation, depended on the lateral distance to the vortex and on the height above the superconductor, at which the spin is almost not affected by vortex fluctuations.
