我们提出了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。具有一个狄拉克费米子的半金属态与表面上的 s 波超导态之间的量子临界点由超对称共形场论描述，是一种膨胀元素。我们预测了超对称临界点处微分电导的精确电压依赖性。
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 the is an element of-expansion. We predict the exact voltage dependence of the differential conductance at the supersymmetric critical point.
