Three-dimensional character of atom-chip-based rf-dressed potentials
J. J. P. van Es, S. Whitlock, T. Fernholz +2
We experimentally investigate the properties of radio-frequency-dressed potentials for Bose-Einstein condensates on atom chips. The three-dimensional potential forms a connected pa…
Fully permanent magnet atom chip for Bose-Einstein condensation
T. Fernholz, R. Gerritsma, S. Whitlock +2
We describe a self-biased, fully permanent magnet atom chip used to study ultracold atoms and to produce a Bose-Einstein condensate (BEC). The magnetic trap is loaded efficiently b…
Condensate splitting in an asymmetric double well for atom chip based sensors
B. V. Hall, S. Whitlock, R. Anderson +2
We report on the adiabatic splitting of a BEC of Rb atoms by an asymmetric double-well potential located above the edge of a perpendicularly magnetized TbGdFeCo film atom ch…
Asymmetric double-well potential for single atom interferometry
A. I. Sidorov, B. J. Dalton, S. M. Whitlock +1
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…
Bose-Einstein condensates on a permanent magnetic film atom chip
B. V. Hall, S. Whitlock, F. Scharnberg +2
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…
A permanent magnetic film atom chip for Bose-Einstein condensation
B. V. Hall, S. Whitlock, F. Scharnberg +2
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…
