Mean-Field Approach to Charge, Orbital, and Spin Ordering in Manganites
Sudhakar Yarlagadda, C. S. Ting
We present a mean-field theory of charge, orbital, and spin ordering in manganites at 50% and 0% dopings by considering Jahn-Teller interaction, nearest-neighbor repulsion, and no…
Spin-charge separation in the single hole doped Mott antiferromagnet
Z. Y. Weng, V. N. Muthukumar, D. N. Sheng +1
The motion of a single hole in a Mott antiferromagnet is investigated based on the t-J model. An exact expression of the energy spectrum is obtained, in which the irreparable phase…
Local Quasiparticle States around an Anderson Impurity in a d-Wave Superconductor: Kondo Effects
Jian-Xin Zhu, C. S. Ting
The Kondo effects of an Anderson impurity embedded into a d-wave superconductor is studied. Within the slave-boson mean-field approach, the derived Bogoliubov-de Gennes equations a…
Effect of unitary impurities in non-STM-types of tunneling in high-T_c superconductors
Jian-Xin Zhu, C. S. Ting, Chia-Ren Hu
Based on an extended Hubbard model, we present calculations of both the local (i.e., single-site) and spatially-averaged differential tunneling conductance in d-wave superconductor…
