摘要:

用隧道光谱直接观测手征超导体涡旋核中的零能马约拉纳态需要比核态间距$Δ^2/eF$更好的能量分辨率。然而,我们表明,它的存在可以决定性地测试通过比较的温度加宽的隧道电导的一个漩涡与一个antivortex即使在温度$T >> Δ^2/eF$。

英文摘要:

Directly observing a zero energy Majorana state in the vortex core of a chiral superconductor by tunneling spectroscopy requires energy resolution better than the spacing between core states $Δ^2/eF$. We show that nevertheless, its existence can be decisively tested by comparing the temperature broadened tunneling conductance of a vortex with that of an antivortex even at temperatures $T >> Δ^2/eF$.
