论文摘要
最近的热导率测量证据证明了磁场诱导的非亚伯旋转液相中的基塔夫材料$α$ - $ \ mathrm {rucl} _ {3} $。尽管该平台是一个很好的Mott绝缘子，但我们提出了实验，以电气探测自旋液体的标志性手性Majorana边缘状态和大量Anyons，包括其异国情调的交换统计。我们专门引入电路，以利用电动系统和Kitaev材料之间的接口，以将电子从前者转换为后者的新兴费米子，从而实现了针对拓扑超导体和分数量子霍尔的变化的变化。在途中，我们在文献中解决了有关相互作用的主要费用的难题，还开发了一个任何人的互动框架框架，该框架结合了非平凡的能量分区效应。我们的结果通过基塔耶材料阐明了通向拓扑量子计算的部分途径。
Recent thermal-conductivity measurements evidence a magnetic-field-induced non-Abelian spin liquid phase in the Kitaev material $α$-$\mathrm{RuCl}_{3}$. Although the platform is a good Mott insulator, we propose experiments that electrically probe the spin liquid's hallmark chiral Majorana edge state and bulk anyons, including their exotic exchange statistics. We specifically introduce circuits that exploit interfaces between electrically active systems and Kitaev materials to `perfectly' convert electrons from the former into emergent fermions in the latter---thereby enabling variations of transport probes invented for topological superconductors and fractional quantum Hall states. Along the way we resolve puzzles in the literature concerning interacting Majorana fermions, and also develop an anyon-interferometry framework that incorporates nontrivial energy-partitioning effects. Our results illuminate a partial pathway towards topological quantum computation with Kitaev materials.
