Description
We present a theory to describe domain formation observed very recently in a quenched 87Rb gas, a typical ferromagnetic spinor Bose system. An overlap factor is introduced to characterize the symmetry breaking of MF=±1 components for the F=1 ferromagnetic condensate. We demonstrate that the domain formation is a coeffect of the quantum coherence and the thermal relaxation. A thermally enhanced quantum oscillation is observed during the dynamical process of the domain formation. And the spatial separation of domains leads to significant decay of the MF=0 component fraction in an initial MF=0 condensate
