Interaction of F =2 Spinor Bose Condensate with Driven External Magnetic Fields
In this letter, we have studied the interaction of F=2 spinor Bose condensate with a combination of staticand sinusoidal magnetic field bl(t) = b0 + bcos(ωt). We find that the tunneling current among spin 0 and spin ±l,spin 0 and spin ±2, spin ±1 and spin ±2 may exhibit the incremental oscillation behavior, which depends on the fieldparameters of the reduced amplitudes of the transverse and the longitudinal magnetic fields respectively. This meansthat the dynamics spin localization can be adjusted experimentally by selecting the less values of the reduced amplitudesof the transverse magnetic field bx/ω and those of the longitudinal magnetic field b/ω.
