我们数值研究原子干涉的基础上自旋交换碰撞在$F=1$旋量玻色-爱因斯坦凝聚体在制度的长演化时间$t\gg h/c$，其中c是自旋相关的相互作用能。我们表明，自旋混合干涉术的灵敏度可以提高通过使用经典的种子初始状态与一个小的人口准备在$mF =\pm1$的状态。
We numerically investigate atomic interferometry based on spin-exchange collisions in $F=1$ spinor Bose-Einstein condensates in the regime of long evolution times $t\gg h/c$, where c is the spin-dependent interaction energy. We show that the sensitivity of spin-mixing interferometry can be enhanced by using classically seeded initial states with a small population prepared in the $m_F=\pm1$ states.
