Excited spin states and phase separation in spinor Bose-Einstein condensates
Excited spin states and phase separation in spinor Bose-Einstein condensates
We analyze the structure of spin-one Bose-Einstein condensates in the presence of a homogeneous magnetic field. We classify the homogeneous stationary states and study their existence, bifurcations, and energy spectra. We reveal that phase separation can occur in the ground state of antiferromagnetic (polar) condensates while the spin components of …
