Temperature and Dimensionality Dependences of Optical Absorption Spectra in Mott Insulators

H. Onodera, T. Tohyama, S. Maekawa

We investigate the temperature dependence of optical absorption spectra of one-dimensional (1D) and two-dimensional (2D) Mott insulators by using an effective model in the strong-c…

Friedel oscillations in a two-band Hubbard model for CuO chains

M. Mori, T. Tohyama, S. Maekawa +1

Friedel oscillations induced by open boundary conditions in a two-band Hubbard model for CuO chains are numerically studied. We find that for physically realistic parameters and cl…

Mott Gap Excitations and Resonant Inelastic X-Ray Scattering in Doped Cuprates

K. Tsutsui, T. Tohyama, S. Maekawa

Predictions are made for the momentum- and carrier-dependent degradation of the Mott gap upon doping in high-Tc cuprates as would be observed in Cu K-edge resonant inelastic x-ray…
