物质波脉冲特征

Matter wave pulses characteristics

A. del Campo, J. G. Muga

摘要:

我们研究了由具有单个或周期性开口的锐边或切趾光闸产生的量子单粒子波脉冲的性质。特别是,我们研究的衍射条纹的可见性取决于演化时间和温度;纯度的状态取决于开放时间窗口;的准确性的简化描述,使用“源”的边界条件,而不是解决初始值问题;和切趾的影响上的能量宽度。

英文摘要:

We study the properties of quantum single-particle wave pulses created by sharp-edged or apodized shutters with single or periodic openings. In particular, we examine the visibility of diffraction fringes depending on evolution time and temperature; the purity of the state depending on the opening-time window; the accuracy of a simplified description which uses ``source'' boundary conditions instead of solving an initial value problem; and the effects of apodization on the energy width.
