量子霍尔态的手征拓扑超导体

Chiral Topological Superconductor From the Quantum Hall State

Xiao-Liang Qi, Taylor L. Hughes, Shou-Cheng Zhang

摘要:

二维手征拓扑超导体在体块中具有完全的配对能隙,在边缘处具有单个手征Majorana态。手征超导态的涡旋具有Majorana零模,这是涡旋的非阿贝尔统计的原因。尽管进行了大量的研究,但这种新的超导态尚未在自然界中被发现。在本文中,我们考虑了一个量子霍尔或量子反常霍尔态附近的平台过渡,并接近一个完全带隙的s波超导体。我们表明,这种混合系统实现了长期以来追求的手征超导状态,并提出了几种实验方法来观察。

英文摘要:

The chiral topological superconductor in two dimensions has a full pairing gap in the bulk and a single chiral Majorana state at the edge. The vortex of the chiral superconducting state carries a Majorana zero mode which is responsible for the non-abelian statistics of the vortices. Despite intensive searches, this novel superconducting state has not yet been identified in nature. In this paper, we consider a quantum Hall or a quantum anomalous Hall state near the plateau transition, and in proximity to a fully gapped s-wave superconductor. We show that this hybrid system realizes the long sought after chiral superconductor state, and propose several experimental methods for its observation.
