自由振荡原子干涉仪的分析

Analysis of a free oscillation atom interferometer

Rudra P. Kafle, Dana Z. Anderson, Alex A. Zozulya

摘要:

我们分析了弱束缚简谐磁阱中基于玻色-爱因斯坦凝聚体(BEC)的自由振荡原子迈克耳孙干涉仪。在陷阱中心的BEC被激光驻波分裂成两个谐波。谐波以相等的速度沿相反的方向移动,并在其经典转折点处的捕获势的影响下折回。谐波被允许通过彼此,并且当它们在第二次返回之后在周期结束时重叠时施加复合脉冲。我们推导出干涉条纹对比度的表达式,并在参数空间中得到干涉仪性能的基本极限。

英文摘要:

We analyze a Bose-Einstein condensate (BEC) - based free oscillation atom Michelson interferometer in a weakly confining harmonic magnetic trap. A BEC at the center of the trap is split into two harmonics by a laser standing wave. The harmonics move in opposite directions with equal speeds and turn back under the influence of the trapping potential at their classical turning points. The harmonics are allowed to pass through each other and a recombination pulse is applied when they overlap at the end of a cycle after they return for the second time. We derive an expression for the contrast of the interferometric fringes and obtain the fundamental limit of performance of the interferometer in the parameter space.
