Schwinger-Boson Mean-Field Theory of Mixed-Spin Antiferromagnet
Yun Song, Shiping Feng
The Schwinger-boson mean-field theory is used to study the three-dimensional antiferromagnetic ordering and excitations in compounds , a large family of quasi-one-dimen…
Convergence of energy-dependent incommensurate antiferromagnetic neutron scattering peaks to commensurate resonance in underdoped bilayer cuprates
Shiping Feng, Feng Yuan, Zhao-Bin Su +1
The recently discovered coexistence of incommensurate antiferromagnetic neutron scattering peaks and commensurate resonance in underdoped YBaCuO is calling for an e…
Pseudogap effects on the charge dynamics in the underdoped copper oxide materials
Shiping Feng, Feng Yuan
Within the t-J model, the charge dynamics of copper oxide materials in the underdoped regime is studied based on the fermion-spin theory. It is shown that both in-plane charge dyna…
Effect of the additional second neighbor hopping on the charge dynamics in the t-J model
Feng Yuan, Shiping Feng
The effect of the additional second neighbor hopping t' on the charge dynamics of the t-J model in the underdoped regime is studied within the fermion-spin theory. The conductivity…
Optical and transport properties in doped two-leg ladder antiferromagnet
Jihong Qin, Yun Song, Shiping Feng +1
Within the t-J model, the optical and transport properties of the doped two-leg ladder antiferromagnet are studied based on the fermion-spin theory. It is shown that the optical an…
Indications of incommensurate spin fluctuations in doped triangular antiferromagnets
Ying Liang, Shiping Feng
The incommensurate spin fluctuation of the doped triangular antiferromagnet is studied within the t-J model. It is shown that the commensurate peak near the half-filling is split i…
