Spin Decoherence in Superconducting Atom Chips
Per Kristian Rekdal, Bo-Sture K. Skagerstam, Ulrich Hohenester, Asier Eiguren
abstract: Using a consistent quantum-mechanical treatment for the electromagnetic
radiation, we theoretically investigate the magnetic spin-flip scatterings of a
neutral two-level atom trapped in the vicinity of a superconducting body. We
derive a simple scaling law for the corresponding spin-flip lifetime for such
an atom trapped near a superconducting thick slab. For temperatures below the
superconducting transition temperature T_c, the lifetime is found to be
enhanced by several orders of magnitude in comparison to the case of a normal
conducting slab. At zero temperature the spin-flip lifetime is given by the
unbounded free-space value.
