Jones, M. P. A. and Vale, C. J. and Sahagun, D. and Hall, B. V. and Hinds, E. A. (2003) 'Spin coupling between cold atoms and the thermal fluctuations of a metal surface.', Physical review letters., 91 (8). 080401.
We describe an experiment in which Bose-Einstein condensates and cold atom clouds are held by a microscopic magnetic trap near a room-temperature metal wire 500 m in diameter. The lifetime for atoms to remain in the microtrap is measured over a range of distances down to 27 m from the surface of the metal.We observe the loss of atoms from the microtrap due to spin flips. These are induced by radio-frequency thermal fluctuations of the magnetic field near the surface, as predicted but not previously observed.
