Current-spin coupling for ferromagnetic domain walls in fine wires
S. E. Barnes, S. Maekawa
The coupling between a current and a domain wall is examined. In the presence of a finite current and the absence of a potential which breaks the translational symmetry, there is a…
Mott gap excitations in twin-free YBa2Cu3O7-d (Tc = 93 K) studied by RIXS
K. Ishii, K. Tsutsui, Y. Endoh +9
Mott gap excitations in the high-Tc superconductor of the optimal doped YBa2Cu3O7-d (Tc = 93 K) have been studied by the resonant inelastic x-ray scattering method. Anisotropic spe…
Excitonic effect on optical response in one-dimensional two-band Hubbard model
H. Matsueda, T. Tohyama, S. Maekawa
Motivated by the gigantic nonlinear optical response in the halogen-bridged Ni-compounds, the underlying electronic states of the compounds are examined in the one-dimensional two-…
Resonant inelastic x-ray scattering study of hole-doped manganites La1-xSrxMnO3 (x=0.2 and 0.4)
K. Ishii, T. Inami, K. Ohwada +8
Electronic excitations near the Fermi energy in the hole doped manganese oxides (La1-xSrxMnO3, x=0.2 and 0.4) have been elucidated by using the resonant inelastic x-ray scattering…
Dynamical density matrix renormalization group study of photoexcited states in one-dimensional Mott insulators
H. Matsueda, T. Tohyama, S. Maekawa
One-dimensional Mott insulators exhibit giant nonlinear optical response. Based on the dynamical density matrix renormalization group method, photoexcited states and optical respon…
