Abstract

We predict that an incompressible fractional quantum Hall state is likely to form at ν = 3/8 as a result of a chiral p-wave pairing of fully spin polarized composite fermions carrying four quantized vortices, and that the pairing is of the anti-Pfaffian kind. Experimental ramifications include quasiparticles with non-Abelian braid statistics and upstream neutral edge modes.

摘要

我们预测，由于携带四个量子涡旋的完全自旋极化复合费米子的手性 p 波配对，在 ν = 3/8 处可能形成不可压缩分数量子霍尔态，并且配对是反 Pfaffian 类型。实验结果包括具有非阿贝尔辫子统计和上游中性边缘模式的准粒子。
