Spatial period-doubling in Bose-Einstein condensates in an optical lattice
M. Machholm, A. Nicolin, C. J. Pethick +1
We demonstrate that there exist stationary states of Bose-Einstein condensates in an optical lattice that do not satisfy the usual Bloch periodicity condition. Using the discrete m…

Band structure, elementary excitations, and stability of a Bose-Einstein condensate in a periodic potential
M. Machholm, C. J. Pethick, H. Smith
We investigate the band structure of a Bose-Einstein condensate in a one-dimensional periodic potential by calculating stationary solutions of the Gross-Pitaevskii equation which h…
