Observation of spin-conserving two-spinon continuum in the =1/2 antiferromagnetic chain system SrCuO using Cu -edge resonant inelastic x-ray scattering
Kenji Ishii, Kenji Tsutsui, Takayuki Kawamata +1
We report a Cu -edge resonant inelastic x-ray scattering (RIXS) study of spin excitations in the =1/2 antiferromagnetic chain system SrCuO. The spectral weight observ…
Spin and charge dynamics of doped one-dimensional Mott insulators
Takami Tohyama, Hiroki Maeda, Kenji Tsutsui +2
Recent angle-resolved photoemission spectroscopy (ARPES) for a newly discovered doped one-dimensional (1D) Mott insulator BaSrCuO proposed the presence of attra…
Exciton-assisted low-energy magnetic excitations in a photoexcited Mott insulator on a square lattice
Kenji Tsutsui, Kazuya Shinjo, Shigetoshi Sota +1
The photoexcitation of a Mott insulator on a square lattice weakens the intensity of both single- and two-magnon excitations as observed in time-resolved resonant-inelastic X-ray s…
Spectral Weight of Resonant Inelastic X-Ray Scattering in Doped Cuprates: Effect of Core-Hole Lifetime
Takami Tohyama, Kenji Tsutsui
We examine the effect of core-hole lifetime on the spectral weight of resonant inelastic x-ray scattering (RIXS) in hole-doped cuprates. We calculate the spectral weight by using e…
Incident-energy-dependent spectral weight of resonant inelastic x-ray scattering in doped cuprates
Kenji Tsutsui, Takami Tohyama
We theoretically investigate the incident-photon energy omega_i dependence of resonant inelastic x-ray scattering (RIXS) tuned for the Cu L edge in cuprate superconductors by using…
Orbital-selective electronic excitations in iron arsenides revealed by simulated nonresonant inelastic x-ray scattering
Kenji Tsutsui, Eiji Kaneshita, Takami Tohyama
Nonresonant inelastic x-ray scattering (NIXS) is a possible tool to detect charge excitations in electron systems. In addition, multipole transitions at high-momentum-transfer regi…
