Localization of Two-Component Bose-Einstein Condensates in Optical Lattices
Localization of Two-Component Bose-Einstein Condensates in Optical Lattices
We study nonlinear localization of a two-component Bose-Einstein condensate (BEC) in a one-dimensional optical lattice. Our theory shows that spin-dependent optical lattices can be used to effectively manipulate the nonlinear interactions between the BEC components, and to observe composite localized states of a BEC in both bands and gaps of …
