Control of quantum interference in semiconductor quantum systems

本研究的目的是观察和控制半导体量子系统的高频响应。我们主要研究了量子霍尔系统中的边缘磁等离子体(EMP)的输运特性，即沿边缘通道传播的电荷密度波。我们研究了电磁脉冲通过量子点接触和电磁脉冲腔体的传输特性，并发展了一些观测和控制电磁脉冲干扰的技术。

The purpose of this research is to observe and control the high-frequency response of semiconductor quantum systems. We focused on transport characteristics of edge-magnetoplasmons (EMPs) in quantum Hall systems, which are charge-density waves traveling along the edge channels. We investigated transmission characteristics of EMPs through quantum point contacts and EMP-cavities and developed some techniques to observe and control the interference of EMPs.
