Theory of RIXS in strongly correlated electron systems: Mott gap excitations in cuprates
T. Tohyama, K. Tsutsui, S. Maekawa
We theoretically examine the momentum dependence of resonant inelastic x-ray scattering (RIXS) spectrum for one-dimensional and two-dimensional cuprates based on the single-band Hu…
Electron-phonon coupling and spin-charge separation in one-dimensional Mott insulators
Hiroaki Matsueda, Takami Tohyama, Sadamichi Maekawa
We examine the single-particle excitation spectrum in the one-dimensional Hubbard-Holstein model at half-filling by performing the dynamical density matrix renormalization group (D…
Charge Imbalance Effects on Interlayer Hopping and Fermi Surfaces in Multilayered High-T_c Cuprates
M. Mori, T. Tohyama, S. Maekawa
We study doping dependence of interlayer hoppings, t_\perp, in multilayered cuprates with four or more CuO_2 planes in a unit cell. When the double occupancy is forbidden in the pl…
Symmetry of Photoexcited States and Large-Shift Raman Scattering in Two-Dimensional Mott Insulators
T. Tohyama
Symmetry of photoexcited states with two photoinduced carriers in two-dimensional Mott insulators is examined by applying the numerically exact diagonalization method to finite-siz…
Nonlinear Optical Response of Spin Density Wave Insulators
S. A. Jafari, T. Tohyama, S. Maekawa
We calculate the third order nonlinear optical response in the Hubbard model within the spin density wave (SDW) mean field ansatz in which the gap is due to onsite Coulomb repulsio…
Temperature dependence of spinon and holon excitations in one-dimensional Mott insulators
Hiroaki Matsueda, Nejat Bulut, Takami Tohyama +1
Motivated by the recent angle-resolved photoemission spectroscopy (ARPES) measurements on one-dimensional Mott insulators, SrCuO and NaVO, we exa…
