Band structure renormalization and weak pseudogap behavior in Na_{0.33}CoO_2: Fluctuation exchange study based on a single band model
Zi-Jian Yao, Jian-Xin Li, Z. D. Wang
Based on a single band Hubbard model and the fluctuation exchange approximation, the effective mass and the energy band renormalization in NaCoO is elaborated. The ren…
Tuning Kinetic Magnetism of Strongly Correlated Electrons via Staggered Flux
Yi-Fei Wang, Chang-De Gong, Z. D. Wang
We explore the kinetic magnetism of the infinite- repulsive Hubbard models at low hole densities on various lattices with nearest-neighbor hopping integrals modulated by a stagg…
Spin-Orbital Entanglement and Phase Diagram of Spin-orbital Chain with Symmetry
Yan Chen, Z. D. Wang, Y. Q. Li +1
Spin-orbital entanglement in quantum spin-orbital systems is quantified by a reduced von Neumann entropy, and is calculated for the ground state of a coupled spin-orbital chain wit…
Symmetry Does Not Allow Canting of Spins in La_{1.4}Sr_{1.6}Mn_2O_7
Fan Zhong, Z. D. Wang
We analyze the symmetry of all possible magnetic structures of bilayered manganites La_{2-2x}Sr_{1+2x}Mn_2O_7 with doping 0.3 <= x < 0.5 and formulate a corresponding Landau theory…
Linear spin and orbital wave theory for undoped manganites
R. Y. Gu, Shun-Qing Shen, Z. D. Wang +1
We present a linear spin and orbital wave theory to account for the spin and orbital orderings observed experimentally in undoped manganite. It is found that the anisotropy of the…
