我们提出了一个实验，通过测量电流噪声来探测分数量子霍尔态准粒子的非常规量子统计。我们考虑的几何结构是一个霍尔杆，其中两个量子点接触引入了两个后向散射的干涉幅度。封闭在两点接触之间的准粒子数量的热波动引入了电流噪声，这反映了准粒子的统计性。我们分析了abel =1/q状态和非abel =5/2状态。
We propose an experiment to probe the unconventional quantum statistics of quasiparticles in fractional quantum Hall states by measurement of current noise. The geometry we consider is that of a Hall bar where two quantum point contacts introduce two interfering amplitudes for backscattering. Thermal fluctuations of the number of quasiparticles enclosed between the two point contacts introduce current noise, which reflects the statistics of the quasiparticles. We analyze Abelian nu=1/q states and the non-Abelian nu=5/2 state.
