Strong Anisotropy of Dirac Cone in SrMnBi2 and CaMnBi2 Revealed by Angle-Resolved Photoemission Spectroscopy
Ya Feng, Zhijun Wang, Chaoyu Chen +18
The Dirac materials, such as graphene and three-dimensional topological insulators, have attracted much attention because they exhibit novel quantum phenomena with their low energy…
Fermi Surface and Band Structure of (Ca,La)FeAs2 Superconductor from Angle-Resolved Photoemission Spectroscopy
Xu Liu, Defa Liu, Lin Zhao +17
The (Ca,R)FeAs2 (R=La,Pr and etc.) superconductors with a signature of superconductivity transition above 40 K possess a new kind of block layers that consist of zig-zag As chains.…
Doping Evolution of Nodal Band Renormalization in Bi2Sr2CuO6+d Superconductor Revealed by Laser-Based Angle-Resolved Photoemission Spectroscopy
Yingying Peng, Jianqiao Meng, Lin Zhao +9

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
