Magnetic Ordering, Orbital Ordering and Resonant X-ray Scattering in Perovskite Titanates
S. Ishihara, T. Hatakeyama, S. Maekawa
The effective Hamiltonian for perovskite titanates is derived by taking into account the three-fold degeneracy of orbitals and the strong electron-electron interactions. T…
A Jordan-Wigner transformation for the and Hubbard models with holes
S. E. Barnes, S. Maekawa
A Jordan-Wigner (JW) transformation for the and Hubbard models is described. Introduced are holon and doublon particles for hole and double occupied sites. There is only a si…
Bi-layer splitting in overdoped high cuprates
S. E. Barnes, S. Maekawa
Recent angle-resolved photoemission data for overdoped Bi2212 are explained. Of the peak-dip-hump structure, the peak corresponds the component of a hole condensate whi…
Theory of Raman Scattering from Orbital Excitations in Manganese Oxides
S. Okamoto, S. Ishihara, S. Maekawa
We present a theory of the Raman scattering from the orbital wave excitations in manganese oxides. Two excitation processes of the Raman scattering are proposed. The Raman scatteri…
Spin transport and relaxation in superconductors
T. Yamashita, S. Takahashi, H. Imamura +1
We study theoretically the effect of spin relaxation on the spin transport in a ferromagnet/superconductor(FM/SC) tunnel junction. When spin-polarized electrons are injected into t…
Electronic Structure of Mott Insulators Studied by Inelastic X-ray Scattering
M. Z. Hasan, E. D. Isaacs, Z-X. Shen +4
The electronic structure of Mott insulators continues to be a major unsolved problem in physics despite more than half-century of intense research efforts. Well-developed momentum-…
