摘要：
We study the coherent spin dynamics of a ferromagnetic spinor Bose–Einstein condensate(BEC)in its domain formation process with an arbitrary spin configuration.Through a simplified schematic view of the domain structure,a semiclassical theory that captures the essential dynamics of the system is presented,and the coherent spin mixing dynamics can be understood in terms of oscillation in the phase space diagram.Using the phase diagram analysis method,we identify new phases,including theπphase oscillation and the running phase for the spin-imbalanced ferromagnetic spinor BEC.
