二维$p$波超导体中的Majorana零模

Majorana Zero-Modes in a Two-Dimensional $p$-Wave Superconductor

Vo Tien Phong, Niels R. Walet, Francisco Guinea

摘要:

我们分析了二维拓扑超导体边缘Majorana零模的形成。特别是,我们研究了时间反演不变的三重态相,这是可能存在于掺杂Bi $_2$ Se $_3$。在超导体中引入面内磁场后,表面模中的能隙被打开,从而诱导出局域化的马约拉纳模。这些模式的位置可以简单地通过改变所施加的场的方向来操纵,从而产生编织这些状态的新方法,这些状态可能应用于拓扑量子计算。

英文摘要:

We analyze the formation of Majorana zero-modes at the edge of a two-dimensional topological superconductor. In particular, we study a time-reversal-invariant triplet phase that is likely to exist in doped Bi$_2$Se$_3$. Upon the introduction of an in-plane magnetic field to the superconductor, a gap is opened in the surface modes, which induces localized Majorana modes. The position of these modes can be simply manipulated by changing the orientation of the applied field, yielding novel methods for braiding these states with possible applications to topological quantum computation.
