| contents | Soliton sheets which are formed by interference of Bose Einstein condensates occupying different single-particle states are observed in optical lattice potential. This structure consists of one-dimensional stationary solitons arranged periodically along the peaks of optical lattice (y direction) with the phase difference between the two sides of the soliton sheets is a linear function of y in each period, so we call it soliton sheet. A y component velocity difference exists between the two sides of the soliton sheet. Similar velocity distributions can be produced by the alignment of an infinite number of isotropic vortices along the peaks of the optical lattice. Their difference is that the soliton sheet structure is not limited by the number of phase singularities and can be generated even without phase singularities. |
