Multi-Triplon Excitations of Hubbard Ladders with Site-Dependent Potentials
Nobuya Maeshima, Ken-ichi Hino
We study low-lying spin-singlet excitations of two-leg Hubbard ladders with site-dependent potentials. Using general formulas of the charge disproportionation induced by the site-d…
Laser induced surface magnetization in Floquet-Weyl semimetals
Runnan Zhang, Ken-ichi Hino, Nobuya Maeshima +2
We investigate optically induced magnetization in Floquet-Weyl semimetals generated by irradiation of a circularly-polarized continuous-wave laser from the group II-V narrow gap se…
Floquet-Weyl semimetals generated by an optically resonant interband-transition
Runnan Zhang, Ken-ichi Hino, Nobuya Maeshima
Floquet-Weyl semimetals (FWSMs) generated by irradiation of a continuous-wave laser with left-hand circular polarization (rotating in counterclockwise sense with time) on the group…
Edge states of Floquet-Dirac semimetal in a laser-driven semiconductor quantum-well
Boyuan Zhang, Nobuya Maeshima, Ken-ichi Hino
Band crossings observed in a wide range of condensed matter systems are recognized as a key to understand low-energy fermionic excitations that behave as massless Dirac particles.…
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…
