Why there is a difference between optimal doping for maximal Tc and critical doping for highest ρ_s in cuprate superconductors?
Zheyu Huang, Huaisong Zhao, Shiping Feng
A long-standing puzzle is why there is a difference between the optimal doping δ_{optimal}=0.15 for the maximal superconducting (SC) transition temperature Tc and the critical dopi…
Impurity effects on the quantum coherence of a few-boson system
Pei Lu, Zhi-Hai Zhang, Shiping Feng +1
The impurity effects on the quantum coherence of a few-boson system are studied within the two-site Hubbard model. Periodical collapses and revivals of coherence occur in the prese…
Pseudogap and its connection to particle-hole asymmetry electronic state and Fermi arcs in cuprate superconductors
Huaisong Zhao, Lulin Kuang, Shiping Feng
The particle-hole asymmetry electronic state of cuprate superconductors and the related doping and temperature dependence of the Fermi arc length are studied based on the kinetic e…
Fractional topological phase in one-dimensional flatbands with nontrivial topology
Huaiming Guo, Shun-Qing Shen, Shiping Feng
We show the existence of the fractional topological phase (FTP) in a one-dimensional interacting fermion model using exact diagonalization, in which the non-interacting part has fl…
Doping dependence of electromagnetic response in electron-doped cuprate superconductors
Zheyu Huang, Huaisong Zhao, Shiping Feng
Within the framework of the kinetic energy driven superconducting mechanism, the doping dependence of the electromagnetic response in the electron-doped cuprate superconductors is…
Analytical solutions to the spin-1 Bose-Einstein condensates
Zhi-Hai Zhang, Cong Zhang, Shi-Jie Yang +1
We analytically solve the one-dimensional coupled Gross-Pitaevskii equations which govern the motion of F=1 spinor Bose-Einstein condensates. The nonlinear density-density interact…
