Nematic orders and nematicity-driven topological phase transition in FeSe
Xianxin Wu, Yi Liang, Heng Fan +1
We investigate nematic states in both bulk FeSe and FeSe thin films. It is found that their band structures and signature features that were observed in a variety of experiments ca…
Staggered FeSe Monolayer on SrTiO (110) surface
Xianxin Wu, Xia Dai, Yi Liang +3
We investigate the electronic and magnetic properties of FeSe monolayer on the anisotropic SrTiO (110) surface. With compressive strain along direction from the s…
Electronic structure properties in the nematic phases of FeSe
Yi Liang, Xianxin Wu, Jiangping Hu
We investigate the electronic structures of FeSe in the presence of different possible orders. We find that only ferro-orbital order (FO) and collinear antiferro-magnetism (C-AFM)…
Topological Characters in Fe(TeSe) thin films
Xianxin Wu, Shengshan Qin, Yi Liang +2
We investigate topological properties in the Fe(Te,Se) thin films. We find that the single layer FeTeSe has nontrivial topological invariance which originates fro…
CaFeAs: a Staggered Intercalation of Quantum Spin Hall and High Temperature Superconductivity
Xianxin Wu, Shengshan Qin, Yi Liang +3
We predict that CaFeAs, a newly discovered iron-based high temperature (T) superconductor, is a staggered intercalation compound that integrates topological quantum spin ha…
-wave Pairing in BiS Superconductors
Xianxin Wu, Jing Yuan, Yi Liang +2
Recent angle resolved photoemission spectroscopy(ARPES) experiments have suggested that BiS based superconductors are at very low electron doping. Using random phase approximat…
The effect of As-Chain layers in CaFeAs
Xianxin Wu, Congcong Le, Yi Liang +3
The new discovered iron-based superconductors have chain-like As layers. These layers generate an additional 3-dimensional hole pocket and cone-like electron pockets. The former is…
Pairing Symmetry in Layered BiS Compounds Driven by Electron-Electron Correlation
Yi Liang, Xianxin Wu, Wei-Feng Tsai +1
We investigate the pairing symmetry of layered BiS compounds by assuming that electron-electron correlation is still important so that the pairing is rather short range. We fin…
