Orbital-Selective Spin Texture and its Manipulation in a Topological Insulator
Zhuojin Xie, Shaolong He, Chaoyu Chen +20
Topological insulators represent a new quantum state of matter that are insulating in the bulk but metallic on the edge or surface. In the Dirac surface state, it is well-establish…
Disappearance of Nodal Gap across the Insulator-Superconductor Transition in a Copper-Oxide Superconductor
Yingying Peng, Jianqiao Meng, Daixiang Mou +16
The parent compound of the copper-oxide high temperature superconductors is a Mott insulator. Superconductivity is realized by doping an appropriate amount of charge carriers. How…
Tunable Dirac Fermion Dynamics in Topological Insulators
Chaoyu Chen, Zhuojin Xie, Ya Feng +21
Three-dimensional topological insulators are characterized by insulating bulk state and metallic surface state involving Dirac fermions that behave as massless relativistic particl…
