B. N. Katz, M. P. Blencowe, K. C. Schwab

摘要:

一个原子附着在一根频率为100 MHz、位移幅度为1 nm的微米级金属丝上,其加速度为10^9 ms^-2,接近于中子星的表面引力。作为这种极端的非惯性力在介观环境中的一个应用,我们考虑了一个模型的双路径原子干涉仪的一个路径组成的100 MHz的振弦原子引导。振动的金属丝导向器用作非惯性参考系,并且在穿过金属丝系的原子的波函数中引起原则上可测量的相移。我们进一步考虑了当振弦被模拟为量子物体,从而作为量子非惯性参考系时,对原子波干涉的影响。我们概述了一种可能实现的振弦,原子干涉仪使用超流氦量子干涉装置。

英文摘要:

An atom attached to a micrometer-scale wire that is vibrating at a frequency of 100 MHz and with displacement amplitude 1 nm experiences an acceleration magnitude 10^9 ms^-2, approaching the surface gravity of a neutron star. As one application of such extreme non-inertial forces in a mesoscopic setting, we consider a model two-path atom interferometer with one path consisting of the 100 MHz vibrating wire atom guide. The vibrating wire guide serves as a non-inertial reference frame and induces an in principle measurable phase shift in the wave function of an atom traversing the wire frame. We furthermore consider the effect on the two-path atom wave interference when the vibrating wire is modeled as a quantum object, hence functioning as a quantum non-inertial reference frame. We outline a possible realization of the vibrating wire, atom interferometer using a superfluid helium quantum interference setup.
