Realization of one-dimensional electronic flat bands in an untwisted moire superlattice

Yafei Li, Qing Yuan, Deping Guo +7

Two-dimensional electronic flat bands and their induced correlated electronic interactions have been discovered, probed, and tuned in interlayer regions of hexagonally shaped van d…

s-Wave-Like excitation in the superconducting state of electron-doped cuprates with d-wave pairing

Qingshan Yuan, Xin-Zhong Yan, C. S. Ting

An intrinsic physical mechanism, based on the doping evolution of the Fermi surface (FS), is explored to reconcile the contradictory experimental results on the superconducting (SC…

Theory of antiferromagnetism in the electron-doped cuprate superconductors

Xin-Zhong Yan, Qingshan Yuan, C. S. Ting

On the basis of the Hubbard model, we present the formulation of antiferromagnetism in electron-doped cuprates using the fluctuation-exchange approach. Taking into account the spin…

Nonmonotonic gap in the coexisting antiferromagnetic and superconducting state for electron-doped cuprate superconductors

Qingshan Yuan, Feng Yuan, C. S. Ting

We argue that the experimentally observed nonmonotonic gap in electron-doped cuprates at optimal doping is the lowest quasiparticle excitation energy in the coexisting antiferromag…

Doping dependence of the electron-doped cuprate superconductors from the antiferromagnetic properties of the Hubbard model

Qingshan Yuan, Feng Yuan, C. S. Ting

Within the Kotliar-Ruckenstein slave-boson approach, we have studied the antiferromagnetic (AF) properties for the --- model applied to electron-doped cuprate superc…

Spin dynamics in the antiferromagnetic phase for electron-doped cuprate superconductors

Qingshan Yuan, T. K. Lee, C. S. Ting

Based on the --- model we have calculated the dynamical spin susceptibilities in the antiferromagnetic (AF) phase for electron-doped cuprates, by use of the slave-bo…
