Two Ferromagnetic States in Magnetoresistive Manganites - First Order Transition Driven by Orbitals -
S. Maekawa, S. Ishihara, S. Okamoto
A systematic study of the electronic structure in perovskite manganites is presented. The effective Hamiltonian is derived by taking into account the degeneracy of orbitals a…

Theory of Orbital Excitation and Resonant Inelastic X-ray Scattering in Manganites
Sumio Ishihara, Sadamichi Maekawa
We study theoretically the collective orbital excitation named orbital wave in the orbital ordered manganites.The dispersion relation of the orbital wave is affected by the static…

Stripe Stability in the Extended t-J Model on Planes and Four-Leg Ladders
T. Tohyama, C. Gazza, C. T. Shih +4
The tendencies to phase-separation and stripe formation of the t-J model on planes and four-leg ladders have been here reexamined including hole hopping terms t', t'' beyond neares…
