Fermi surface topology and low-lying electronic structure of a new iron-based superconductor Ca10(Pt3As8)(Fe2As2)5
M. Neupane, Chang Liu, S. -Y. Xu +9
We report a first study of low energy electronic structure and Fermi surface topology for the recently discovered iron-based superconductor Ca10(Pt3As8)(Fe2As2)5 (the 10-3-8 phase,…
Electron dynamics in topological insulator based semiconductor-metal interfaces (topological p-n interface based on Bi2Se3 class)
L. Andrew Wray, Suyang Xu, Madhab Neupane +10
Single-Dirac-cone topological insulators (TI) are the first experimentally discovered class of three dimensional topologically ordered electronic systems, and feature robust, massl…
A new experimental approach for the exploration of topological quantum phenomena : Topological Insulators and Superconductors
M. Zahid Hasan, David Hsieh, Yuqi Xia +3
The three-dimensional topological insulator (originally called "topological insulators") is the first example in nature of a topologically ordered electronic phase existing in thre…
Spin-orbital groundstates of Superconducting doped topological insulators (A Majorana Platform)
L. Andrew Wray, Yuqi Xia, Su-Yang Xu +8
The BiSe class of topological insulators has recently been shown to undergo a superconducting transition upon hole or electron doping (Cu-BiSe with T=3.8$^o…
Observation of topological order in a Superconducting doped topological insulator (based on the Bi2Se3 class)
L. Andrew Wray, Suyang Xu, Yuqi Xia +7
Topological insulators embody a new state of matter characterized entirely by the topological invariants of the bulk electronic structure rather than any form of spontaneously brok…
Topological Phase Transition and Texture Inversion in a Tunable Topological Insulator
Su-Yang Xu, Y. Xia, L. A. Wray +9
The recently discovered three dimensional or bulk topological insulators are expected to exhibit exotic quantum phenomena. It is believed that a trivial insulator can be twisted in…
