论文摘要
侧重于量子厅(QH)边缘通道中的热传输的研究成功地解决了围绕QH物理学的基本理论问题。但是,边缘耗散现象从边缘的现象变得复杂,并且缺乏治疗这种耗散的理论。还需要更多的实验数据来确定能量离开边缘通道的耦合机制。我们开发了一种绘制QH边缘热传输的方法,以研究热的耗散。我们局部加热了QH边缘,并局部检测到温度升高,同时不断改变加热器和温度计之间的距离。因此,我们获得了边缘状态的热衰减长度。
Research focused on heat transport in the quantum Hall (QH) edge channel has successfully addressed fundamental theoretical questions surrounding the QH physics. However, the picture of the edge channel is complicated by the phenomenon of energy dissipation out of the edge, and theories treating this dissipation are lacking. More experimental data is also needed to determine the coupling mechanism by which energy leaves the edge channel. We developed a method to map the heat transport in the QH edge to study the dissipation of heat. We locally heated the QH edge and locally detected the temperature increase while continuously varying the distance between heater and thermometer. We thereby obtained the thermal decay length of the edge state.
