In this paper, we give the normal and abnormal Bloch states at the Brillouin zone edge to a spin–orbit (SO) coupled Bose–Einstein condensate (BEC) with a high-frequency driving and confined in a periodic lattice. The generation of the spatiotempo

We study the exact Bloch states of a spin-orbit (SO) coupled Bose-Einstein condensate (BEC) held in an optical lattice. Under a natural condition of the symmetry between the two species, we obtain two different forms of exact solutions corresponding

We investigate the chaotic dynamics of a coupled three-level atom–molecular Bose–Einstein condensate system composed by one molecular mode and two atomic modes. With the increase of atom–molecular coupling strength, we reveal the emergence of c
