Peak-structure in self-energy of cuprate superconductors
Yiqun Liu, Yu Lan, Shiping Feng
The recently deduced normal and anomalous self-energies from photoemission spectra of cuprate superconductors via the machine learning technique are calling for an explanation. Her…
Renormalization of electrons in bilayer cuprate superconductors
Yiqun Liu, Yu Lan, Yingping Mou +1
The characteristic features of the renormalization of the electrons in the bilayer cuprate superconductors are investigated within the kinetic-energy driven superconductivity. It i…
Asymmetric doping dependence of superconductivity between hole- and electron-doped triangular-lattice superconductors
Yu Lan, Xixiao Ma, Ling Qin +2
Within the framework of kinetic-energy-driven superconductivity, the asymmetric doping dependence of superconductivity between the hole- and electron-doped triangular-lattice super…
Momentum and doping dependence of spin excitations in electron-doped cuprate superconductors
Pengfei Jing, Huaisong Zhao, Lulin Kuang +2
Superconductivity in copper oxides emerges on doping holes or electrons into their Mott insulating parent compounds. The spin excitations are thought to be the mediating glue for t…
Charge dynamics in doped Mott insulators on a honeycomb lattice
Xixiao Ma, Yu Lan, Ling Qin +1
Within the framework of the fermion-spin theory, the charge transport in the doped Mott insulators on a honeycomb lattice is studied by taking into account the pseudogap effect. It…
Thermodynamic properties in triangular-lattice superconductors
Xixiao Ma, Ling Qin, Huaisong Zhao +2
The study of superconductivity arising from doping a Mott insulator has become a central issue in the area of superconductivity. Within the framework of the kinetic-energy-driven s…
