我们提出了一种利用准一维（1D）波导中的超冷原子反向传播波包来模拟介观输运过程的方法，并与分析结果显示出定量一致性。该方法允许在单个模式的水平上研究广泛的运输过程，这在电子系统中是不可能的。通常被抑制的量子相干效应以及可调谐相互作用的效应变得明显，可用于开发更简单类型的灵敏原子干涉仪。
We propose a way to simulate mesoscopic transport processes with counterpropagating wave packets of ultracold atoms in quasi-one-dimensional (1D) waveguides and show quantitative agreement with analytical results. The method allows the study of a broad range of transport processes at the level of individual modes, not possible in electronic systems. Typically suppressed effects of quantum coherence become manifest, along with the effects of tunable interactions, which can be used to develop a simpler type of sensitive atom interferometer.
