Impurity-induced bound states in superconductors with topological order
Fei Wang, Qin Liu, Tianxing Ma +1
The study of classical spins in topological insulators [Phys. Rev. B {\bf 80}, 115216 (2009)] is generalized to topological superconductors. Based on the characteristic features of…
Stationary phase approach to the quasiparticle interference on the surface of three dimensional strong topological insulators
Qin Liu
Constant energy contour (CEC) of the surface bands in topological insulators varies not only with materials but also at different energies. The quasiparticle interference caused by…
Evolutions of helical edge states in disordered HgTe/CdTe quantum wells
Liang Chen, Qin Liu, Xulin Lin +2
We study the evolutions of the nonmagnetic disorder-induced edge states with the disorder strength in the HgTe/CdTe quantum wells. From the supercell band structures and wave-funct…
Giant topological magnetoelectric and optical Hall effects for topological insulator as a defect in photonic crystal
Peng Wang, Qin Liu, Wei Li +1
A system with a topological insulator slab sandwiched by two one-dimensional photonic crystals as a defect is investigated. A giant topological magnetoelectric effect is proposed w…
