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…
Antiferromagnetism, -wave and chiral -wave superconductivity in a Kagome lattice with possible application to -graphenes
Wan-Sheng Wang, Yuan-Chun Liu, Yuan-Yuan Xiang +1
We investigate the electronic instabilities in a Kagome lattice with Rashba spin-orbital coupling by the unbiased singular-mode functional renormalization group. At the parent $1/3…
Pairing with dominant triplet component and possible weak topological superconductivity in BiS-based superconductors
Y. Yang, W. S. Wang, Y. Y. Xiang +2
We show that the newly discovered BiS-based superconductors may have a dominant triplet pairing component, in addition to a subdominant singlet component arising from the spin-…
In-Gap Quasiparticle Excitations Induced by Non-Magnetic Cu Impurities in Na(Fe0.96Co0.03Cu0.01)As Revealed by Scanning Tunneling Spectroscopy
Huan Yang, Zhenyu Wang, Delong Fang +5
The pairing mechanism in the iron pnictides remains unresolved yet. One of the central issues is the structure of the superconducting order parameter which classifies the community…
Functional renormalization group study of the pairing symmetry and pairing mechanism in iron-selenide superconductors
Yuan-Yuan Xiang, Yang Yang, Wan-Sheng Wang +2
In iron selenide superconductors only electron-like Fermi pockets survive, challenging the pairing based on the quasi-nesting between the electron and hole Fermi pockets…
High superconductivity at the FeSe/SrTiO Interface
Fa Wang, Yuan-Yuan Xiang, Da Wang +2
In a recent experiment the superconducting gap of a single unit cell thick FeSe film on SrTiO substrate is observed by scanning tunneling spectroscopy and angle-resolved photoe…
Time reversal invariant topological superconductivity in correlated non-centrosymmetric systems
Yuan-Yuan Xiang, Wan-Sheng Wang, Qiang-Hua Wang +1
Using functional renormalization group method, we study the favorable condition for electronic correlation driven time reversal invariant topological superconductivity in symmetry…
Functional renormalization group and variational Monte Carlo studies of the electronic instabilities in graphene near 1/4 doping
Wan-Sheng Wang, Yuan-Yuan Xiang, Qiang-Hua Wang +3
We study the electronic instabilities of near 1/4 electron doped graphene using the functional renormalization group (FRG) and variational Monte-Carlo method. A modified FRG implem…
