论文摘要
拓扑边缘通道之间的耦合开放电子相位,其非平凡的本征码远远超出了非互动边缘图片。但是,非弹性散射掩盖了本征码的固有特征,通常会阻止我们识别相位,就像典型的Landau级填充因子v = 2/3边缘的情况一样,由反启动V = 1/3和1(1/3-1)通道组成。在这里,我们通过使用新的设备体系结构对通道长度进行调谐原位,研究1/3-1通道的相干 - 触发器,该结构包括v = 1/3和1个系统,即2/3边缘的粒子 - 偶联物。我们成功地观察了波动导电的同时以及跨界型中的量化导热,这是在疾病主导的边缘相位的特征码的确定标志,左侧左侧的边缘相位实验未验证。
Couplings between topological edge channels open electronic phases possessing nontrivial eigenmodes far beyond the noninteracting-edge picture. However, inelastic scatterings mask the eigenmodes' inherent features, often preventing us from identifying the phases, as is the case for the quintessential Landau-level filling factor v = 2/3 edge composed of the counter-propagating v = 1/3 and 1 (1/3-1) channels. Here, we study the coherent-incoherent crossover of the 1/3-1 channels by tuning the channel length in-situ using a new device architecture comprising a junction of v = 1/3 and 1 systems, the particle-hole conjugate of the 2/3 edge. We successfully observed the concurrence of the fluctuating electrical conductance and the quantized thermal conductance in the crossover regime, the definitive hallmark of the eigenmodes in the disorder-dominated edge phase left experimentally unverified.
