摘要:

最近对$ν=5/2$分数量子霍尔态的半整数热导的测量证实了它的非阿贝尔性质,使得潜在的拓扑序问题非常有趣。我们分析了三个最突出的非阿贝尔候选状态的边缘处的散粒噪声。我们表明,相对于边缘长度的噪声缩放,结合热导率,可用于实验区分Pfweian,反Pfweian,和粒子孔Pfweian边缘结构。

英文摘要:

The recent measurement of a half-integer thermal conductance for the $ν=5/2$ fractional quantum Hall state has confirmed its non-Abelian nature, making the question of the underlying topological order highly intriguing. We analyze the shot noise at the edge of the three most prominent non-Abelian candidate states. We show that the noise scaling with respect to the edge length can, in combination with the thermal conductance, be used to experimentally distinguish between the Pfaffian, anti-Pfaffian, and particle-hole-Pfaffian edge structures.
