Tunneling effect of the spin-2 Bose condensate driven by external magnetic fields

Abstract

In this paper, we have studied tunneling effect of the spin-2 Bose condensate driven by external magnetic field. We find that the population transfers among spin-0 and spin-±1, spin-0 and spin-±2 exhibit the step structure under the external cosinusoidal magnetic field respectively , but there do not exist step structure among spin-±1 and spin-±2.
