Ultracold atoms in an optical lattice with dynamically variable periodicity
S. Al-Assam, R. A. Williams, C. J. Foot
The use of a dynamic "accordion" lattice with ultracold atoms is demonstrated. Ultracold atoms of Rb are trapped in a two-dimensional optical lattice, and the spacing of the…

Observation of vortex nucleation in a rotating two-dimensional lattice of Bose-Einstein condensates
R. A. Williams, S. Al-Assam, C. J. Foot
We report the observation of vortex nucleation in a rotating optical lattice. A 87Rb Bose-Einstein condensate was loaded into a static two-dimensional lattice and the rotation freq…
