Asymmetric double-well potential for single atom interferometry (2006)
Sidorov, A. I., Dalton, B. J., Whitlock, S. M., Scharnberg, F.
We consider the evolution of a single-atom wavefunction in a time-dependent double-well interferometer in the presence of a spatially asymmetric potential. We examine a case where a single trapping...
Bose-Einstein condensates on a permanent magnetic film atom chip (2005)
Hall, B. V., Whitlock, S., Scharnberg, F., Hannaford, P., Sidorov, A.
We present a permanent magnetic film atom chip based on perpendicularly magnetized TbGdFeCo films. This chip routinely produces a Bose-Einstein condensate (BEC) of 10^5 87Rb atoms using the magnetic...
A permanent magnetic film atom chip for Bose-Einstein condensation (2005)
Hall, B. V., Whitlock, S., Scharnberg, F., Hannaford, P., Sidorov, A.
We present a hybrid atom chip which combines a permanent magnetic film with a micromachined current-carrying structure used to realize a Bose-Einstein condensate. A novel TbGdFeCo material with large...
