Abstract
The interaction of BEC with the lattice potential that was analogous to the light scattering by a nonlinear photonic band-gap structure was demonstrated. The properties of two-dimensional atomic band gap structures was studied and demonstrated the existence of gap solitons, the spatially localized states of BEC existing in the gaps of the matter-wave spectrum. It was believed that the analogy between the physics of BEC in optical lattices and photonic crystals can be useful for revealing many novel features of the matter-wave dynamics in reconfigurable atomic band-gap structures.
