Spectral properties of the square-lattice antiferromagnetic J1-J2 Heisenberg model: confinement and deconfinement of spinons
Shun-Li Yu, Wei Wang, Zhao-Yang Dong +2
Based on the mapping between spin operators and hard-core bosons, we extend the cluster perturbation theory to spin systems and study the whole excitation spectrum of the a…
Possible singlet and triplet superconductivity on honeycomb lattice
Long-Yun Xiao, Shun-Li Yu, Wei Wang +2
We study the possible superconducting pairing symmetry mediated by spin and charge fluctuations on the honeycomb lattice using the extended Hubbard model and the random-phase-appro…
Consistent picture of the octet-nodal gap and its evolution with doping in heavily overdoped BaKFeAs
Shun-Li Yu, Zi-Jian Yao, Jian-Xin Li
We investigate the pairing symmetry in heavily overdoped BaKFeAs based on the spin-fluctuation mechanism. The exotic octet nodes of the superconducting ga…
Theory for charge and orbital density-wave states in manganite LaSrMnO
Zi-Jian Yao, Wei-Qiang Chen, Jin-Hua Gao +2
We investigate the high temperature phase of layered manganites, and demonstrate that the charge-orbital phase transition without magnetic order in LaSrMnO can…
Zn-impurity effect and interplay of - and -pairings in Fe-based superconductors
Zi-Jian Yao, Wei-Qiang Chen, Yu-ke Li +5
We report theoretical and experimental studies of the effect of Zn-impurity in Fe-based superconductors. Zn-impurity is expected to severely suppress sign reversed s wave pai…
Single nonmagnetic impurity resonance in FeSe-based 122-type superconductors as a probe for pairing symmetry
Qian-En Wang, Zi-Jian Yao, Fu-Chun Zhang
We study the effect of a single non-magnetic impurity in AFeSe (A=K, Rb, or Cs) superconductors by considering various pairing states based on a three-orbital m…
