局域量子源的物质波

Matter waves from localized quantum sources

Tobias Kramer

摘要:

在物理学中,起源于空间局部区域的物质波是常见的现象。例如光电子、纳米技术设备中的弹道电子(扫描隧道显微镜、量子霍尔效应)或从相干源(原子激光器)释放的原子。我们引入能量相关的格林函数作为一个合适的工具来计算产生的电流。对于某些系统的实验数据是可用的,并与所提出的结果非常一致。

英文摘要:

Matter waves originating from a localized region in space appear commonly in physics. Examples are photo-electrons, ballistic electrons in nanotechnology devices (scanning-tunneling microscopy, quantum Hall effect), or atoms released from a coherent source (atom laser). We introduce the energy-dependent Green function as a suitable tool to calculate the arising currents. For some systems experimental data is available and in excellent agreement with the presented results.
