Aharonov-Bohm干涉术是研究量子霍尔效应中任意子统计的最直接的方法。该技术涉及电流作为磁场的函数的振荡，并且不适用于Kitaev自旋液体和其他没有带电准粒子的系统。在这里，我们建立了一个新的协议，涉及热传输，揭示分数统计，即使在没有带电的激发，是在量子自旋液体的情况下。具体来说，我们证明了Kitaev自旋液体中的热输运通过两个不同的干涉仪的几何形状，法布里-珀罗和马赫-曾德尔，表现出截然不同的行为。因此，我们建议使用热输运干涉法作为探针的电荷绝缘体中的任意子统计。
Aharonov-Bohm interferometry is the most direct probe of anyonic statistics in the quantum Hall effect. The technique involves oscillations of the electric current as a function of the magnetic field and is not applicable to Kitaev spin liquids and other systems without charged quasiparticles. Here, we establish a novel protocol, involving heat transport, for revealing fractional statistics even in the absence of charged excitations, as is the case in quantum spin liquids. Specifically, we demonstrate that heat transport in Kitaev spin liquids through two distinct interferometer’s geometries, Fabry-Perot and Mach-Zehnder, exhibit drastically different behaviors. Therefore, we propose the use of heat transport interferometry as a probe of anyonic statistics in charge insulators.
