Monolayer NbF: a -analogue of cuprates
Yang Yang, Wan-Sheng Wang, C. S. Ting +1
The electronic structure and possible electronic orders in monolayer NbF are investigated by density functional theory and functional renormalization group. Because of the niob…
Chiral and helical -wave superconductivity in doped bilayer BiH
L. Yang, W. S. Wang, D. Wang +1
We investigate the superconductivity (SC) driven by correlation effects in electron-doped bilayer BiH near a type-II van Hove singularity (vHS). By functional renormalization group…
Theory of chiral -wave superconductivity with near-nodes for SrRuO
Wan-Sheng Wang, Cong-Cong Zhang, Fu-Chun Zhang +1
We use functional renormalization group method to study a three-orbital model for superconducting SrRuO. Although the pairing symmetry is found to be chiral -wave, the a…
Superconductivity in SrRuO thin film under biaxial strain
Yuan-Chun Liu, Wan-Sheng Wang, Fu-Chun Zhang +1
Motivated by the success of experimental manipulation of the band structure through biaxial strain in SrRuO thin film grown on a mismatched substrate, we investigate theore…
Electronic orders near the type-II van Hove singularity in BC
Yao Wang, Jin-Guo Liu, Wan-Sheng Wang +1
Using the functional renormalization group, we investigate the electron instability in the single-sheet BC when the electron filling is near a type-II van Hove singularity. For…
Possible Superconductivity in Electron-doped Chromium Pnictide LaOCrAs
Wan-Sheng Wang, Miao Gao, Yang Yang +2
We constructed an effective tight-binding model with five Cr orbitals for LaOCrAs according to first-principles calculations. Basing on this model, we investigated possible su…
