我们提出了一种诱导Z(3)准费米子模的方案,Z(3)准费米子模是一种具有非阿贝尔统计特性的奇异零能束缚态。我们考虑一种最小的设置,由四条隧道耦合的纳米线组成,这些纳米线承载着相互作用强烈的无自旋电子。我们的装置的特点是它只依赖于简单的一维导线、均匀的磁场和强烈的相互作用,而不需要超导或奇异的量子霍尔相的存在。
We propose a scheme to induce Z(3) parafermion modes, exotic zero-energy bound states that possess non-Abelian statistics. We consider a minimal setup consisting of a bundle of four tunnel coupled nanowires hosting spinless electrons that interact strongly with each other. The hallmark of our setup is that it relies only on simple one-dimensional wires, a uniform magnetic field, and strong interactions, but does not require the presence of superconductivity or exotic quantum Hall phases.
