摘要:

微尺度导体的热控持续改进为探测强相关电子现象提供了新的工具。受这些进展的启发,我们全面研究了在分数量子霍尔 regime 中量子点接触装置中的温度偏置引起的输运。我们计算了电荷电流噪声(所谓的 delta-T 噪声)、热电流噪声以及混合噪声,并阐明了这些可观测变量如何用于推断设备的强相关性质。我们的主要关注点是提取所谓的标量维度,这对正确推断隧道任何子 quasi-particles 的任何子交换统计至关重要。

英文摘要:

Continued improvement of heat control in mesoscopic conductors brings novel tools for probing strongly correlated electron phenomena. Motivated by these advances, we comprehensively study transport due to a temperature bias in a quantum point contact device in the fractional quantum Hall regime. We compute the charge-current noise (so-called delta-$T$ noise), heat-current noise, and mixed noise and elucidate how these observables can be used to infer strongly correlated properties of the device. Our main focus is the extraction of so-called scaling dimensions of the tunneling anyonic quasiparticles, of critical importance to correctly infer their anyonic exchange statistics.
