Nonlinear periodic waves and their stabilities for a Bose–Einstein condensate in a nonlinear lattice

We investigate a special class of nonlinear periodic waves and their stabilities for a Bose–Einstein condensate in a pure cosine nonlinear lattice. It is shown that for a specific range of the lattice parameters, we can obtain two different types of exact periodic waves, one-period and double-period...
