Excitonic effects on high-harmonic generation in Mott insulators
Mina Udono, Koudai Sugimoto, Tatsuya Kaneko +1
To study excitonic effects on high-harmonic generation (HHG) in Mott insulators, we investigate pumped nonequilibrium dynamics in the one-dimensional extended Hubbard model. By emp…

Collective mode excitations and simulated -edge resonant-inelastic x-ray scattering spectra in antiferromagnetic CaRuO
Shunsuke Yamamoto, Yukinori Ohta, Koudai Sugimoto
Using the three-orbital Hubbard model, we investigate the low-energy excitation spectra in the antiferromagnetic phase of CaRuO. We calculate the dynamical susceptibilities…
