Abstract
We study the semiclassical dynamics of a spinor condensate with the magnetic dipole–dipole interaction included. The time evolution of the population imbalance and the relative phase among different spin components depend greatly on the relative strength of interactions as well as on the initial conditions. The interplay of spin-exchange and dipole–dipole interaction makes it possible to manipulate the atomic population on different components, leading to the phenomena of spontaneous magnetization and macroscopic quantum self-trapping. A simple estimate demonstrates that these effects are accessible and controllable by modifying the geometry of the trapping potential.
