Abstract

We suggest and study the stable disk- and cigar-shaped gap solitons of a dipolar Bose-Einstein condensate of 52^{52}Cr atoms localized in the lowest band gap by three optical-lattice (OL) potentials along orthogonal directions. The one-dimensional version of these solitons of experimental interest confined by an OL along the dipole moment direction and harmonic traps in transverse directions is also considered. Important dynamics of (i) breathing oscillation of a gap soliton upon perturbation and (ii) dragging of a gap soliton by a moving lattice along axial zz direction demonstrates the stability of gap solitons. A movie clip of dragging of three-dimensional gap soliton is included.
