Dynamical Properties of Spin-Orbital Chains in a Magnetic Field
Weiqiang Yu, Stephan Haas
The excitation spectrum of the one-dimensional spin-orbital model in a magnetic field is studied, using a recently developed dynamical density matrix renormalization group techniqu…

Charge dynamics in doped triangular antiferromagnets
W. Q. Yu, Shiping Feng, Z. B. Huang +1
Within the framework of the fermion-spin theory based on the charge-spin separation, the charge dynamics of the doped antiferromagnet on a triangular lattice is studied. The holon…

Pseudogap effects on the c-axis charge dynamics in copper oxide materials
Shiping Feng, Feng Yuan, Weiqiang Yu
The c-axis charge dynamics of copper oxide materials in the underdoped and optimally doped regimes has been studied by considering the incoherent interlayer hopping. It is shown th…
