Bloch function description of a Bose-Einstein condensate in a finite optical lattice
M. J. Steel, Weiping Zhang
We consider stationary and propagating solutions for a Bose-Einstein condensate in a periodic optical potential with an additional confining optical or magnetic potential. Using an…

Photonic band gaps and defect states induced by excitations of Bose-Einstein condensates in optical lattices
Karl-Peter Marzlin, Weiping Zhang
We study the interaction of a Bose-Einstein condensate, which is confined in an optical lattice, with a largely detuned light field propagating through the condensate. If the conde…

Acceleration of quasi-particle modes in Bose-Einstein condensates
Karl-Peter Marzlin, Weiping Zhang
We analytically examine the dynamics of quasi-particle modes occuring in a Bose-Einstein condensate which is subject to a weak acceleration. It is shown that the momentum of a quas…
