Abstract

Bose-Einstein condensation in trapped dilute gases was first observed in 1995 [1]. As an application of such Bose-Einstein condensates we study the influence of a spatially periodic external potential on the properties of the condensate. Such a periodic potential may be induced by a far-off resonant laser field, and with present trapped condensates it is possible to have a condensate extending over many periods of such a field.
