HgTe quantum wells above a critical thickness are 2-dimensional topological insulators. The most prominent signature of the non-trivial topology in these systems is the occurrence of the quantum spin Hall effect
quantum spin Hall effect 2007年在HgTe中看到了量子自旋霍尔效应[21]。 现在做一个有趣的操作:修改 H_s ,保持gapped和time reversal symmetry: 在\vec n的调控下,分块对角的两部分交换位置,我们称 H_S(\vec k,\vec {e_z})与H_S(\vec k,-\vec {e_z})是时间反演对称性意义下的拓扑等价,此时自旋...

Such protected edge modes and the resulting quantum spin Hall effect (QSHE) have been observed in the HgTe quantum wells (König et al., 2007) and many other systems (Hasan and Kane, 2010). Graphene and other electron systems with intrinsic spin-orbital coupling have been used as examples...
