三维拓扑绝缘体表面超对称性的出现

Emergence of supersymmetry on the surface of three dimensional topological insulators

Pedro Ponte, Sung-Sik Lee

摘要:

本文提出了在三维拓扑绝缘体表面量子临界点处2+1维时空超对称性的两种可能的实验实现。用$ε$展开式的超对称共形场论描述了表面上含有一个狄拉克费米子的半金属态和s波超导态之间的量子临界点.我们预测了微分电导在超对称临界点的精确电压依赖性。

英文摘要:

We propose two possible experimental realizations of a 2+1 dimensional spacetime supersymmetry at a quantum critical point on the surface of three dimensional topological insulators. The quantum critical point between the semi-metallic state with one Dirac fermion and the s-wave superconducting state on the surface is described by a supersymmetric conformal field theory within $ε$-expansion. We predict the exact voltage dependence of the differential conductance at the supersymmetric critical point.
