Long Wavelength Spin Dynamics of Ferromagnetic Condensates

Abstract

The novel dynamics associated with the spin degrees of freedom is one of the most exciting and still relatively unexplored aspects of the physics of ultracold atomic gases. In this talk I will give the effective description of spin dynamics valid in the incompressible limit in a ferromagnetic Bose condensate. The resulting equations of motion will then be used to discuss the stability of magnetic spirals, topological defects, and Larmor precession in the presence of dipolar forces.
