Dynamical Charge Structure Factor of a One-Dimensional Ionic Hubbard Model in the Low-Energy Region
Yuhei Komaki, Yuma Iwase, Shogo Yanagimatsu +3
We present a numerical study of the charge dynamical structure factor N(k,omega) of a one-dimensional (1D) ionic Hubbard model in the Mott insulator phase. We show that the low-ene…

Ultrafast asymmetric Rosen-Zener-like coherent phonon responses observed in silicon
Yohei Watanabe, Ken-ichi Hino, Nobuya Maeshima +2
We investigate the spectral profiles of time signals attributed to coherent phonon generation in an undoped Si crystal. Here, the retarded longitudinal-optical (LO) phonon Green fu…
