We study the statics and dynamics of anisotropic bright solitons in quasi-two-dimensional BECs consisting of polarized dipolar atoms. We study the collision dynamics of two such solitons at different velocities for different angles between the polarization and collision directions. The collision is found to be quasi elastic at large velocities. At small velocities the collision is inelastic leading to the formation of a coalesced soliton in an excited scissors mode, monopole mode or quadrupole mode. Also, at small velocities, after collision, a large change of direction of motion of the solitons is possible. The investigation is performed through a numerical solution of the underlying mean-field Gross–Pitaevskii equation.
