我们报告的超冷原子的光镊输运在非绝热制度，即在时间尺度上的振荡周期的顺序。我们已经发现了一组离散的运输持续时间的运输是不伴随着运输后的云的质量中心的任何激励。我们证明了偶极模的剩余振幅由速度方程的傅里叶变换给出。为了运输，我们把它装进陷阱里。这种形式主义导致对我们的数据的简单解释和优化非绝热状态下被困粒子位移的简单方法。版权所有（c）EPLA，2008年。
We report the transport of ultracold atoms with optical tweezers in the non-adiabatic regime, i.e. on a time scale on the order of the oscillation period. We have found a set of discrete transport durations for which the transport is not accompanied by any excitation of the centre of mass of the cloud after the transport. We show that the residual amplitude of oscillation of the dipole mode is given by the Fourier transform of the velocity pro. le imposed to the trap for the transport. This formalism leads to a simple interpretation of our data and simple methods for optimizing trapped particles displacement in the non-adiabatic regime. Copyright (c) EPLA, 2008.
