Anomalous isotope effect in phonon-dressed iron-based superconductor
Wen-Min Huang, Hong-Yan Shih, Fa Wang +1
The role of electron-phonon interactions in iron-based superconductor is currently under debate with conflicting experimental reports on the isotope effect. To address this importa…
Two-orbital Schwinger Boson Representation of Spin-One: Application to a Non-abelian Spin Liquid with Quaternion Gauge Field
Fa Wang, Cenke Xu
A non-abelian spin liquid in triangular lattice spin-1 systems was recently formulated in the form of continuum field theory [T. Grover, and T. Senthil, Phys. Rev. Lett. 107, 07720…
Spin Liquid Phases for Spin-1 systems on the Triangular lattice
Cenke Xu, Fa Wang, Yang Qi +2
Motivated by recent experiments on material Ba3NiSb2O9, we propose two novel spin liquid phases (A and B) for spin-1 systems on a triangular lattice. At the mean field level, both…
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…
Nearly flat band with Chern number C=2 on the dice lattice
Fa Wang, Ying Ran
We point out the possibility of nearly flat band with Chern number C=2 on the dice lattice in a simple nearest-neighbor tightbinding model. This lattice can be naturally formed by…
The Electron Pairing of KFeSe
Fa Wang, Fan Yang, Miao Gao +3
We studied the pairing instabilities in KFeSe using a two stage functional renormalization group (FRG) method. Our results suggest the leading and subleading pairin…
