Period-doubling Instability of Bose-Einstein Condensates Induced in Periodically Translated Optical Lattices
Abstract
We observe the formation of momentum distributions indicative of spatial period-doubling of superfluid Bose-Einstein condensates in periodically translated optical lattices. The effect is attributed to dynamic instability of the condensate wavefunction caused by modulation-induced coupling of ground and excited bands.
