Abstract: | We numerically simulate the dynamics of a spin-2 Bose-Einstein condensate. We find that the initial phase plays an important role in the spin component oscillations. The spin mixing processes can fully cancel out due to quantum interference when taking some
initial special phase. In all the spin mixing processes, the total spin is conversed. When the initial population is mainly occupied by a component with the maximal or minimal magnetic quantum
number, the oscillations of spin components cannot happen due to
the total spin conversation. The presence of quadratic Zeeman
energy terms suppresses some spin mixing processes so that the
oscillations of spin components are suppressed in some initial
spin configuration. However, the linear Zeeman energy terms have
no effects on the spin mixing processes. |
