Microscopic Origin of Dephasing in Solids from First-Principles Electron-Phonon Interactions
Atsushi Yamada, Kazuhiro Yabana
Electron-phonon interactions provide a microscopic origin of effective dephasing in solids within real -time TDDFT via a time-domain Williams-Lax framework. In metals, Drude -like…
Interaction of intense ultrashort laser pulses with solid targets: A systematic analysis using first-principles calculations
Atsushi Yamada, Kazuhiro Yabana
Intense ultrashort laser pulse irradiation of solid targets was systematically investigated at the first-principles level, both theoretically and computationally. In the method, th…
Nonlinear dynamics of electromagnetic field and valley polarization in WSe monolayer
Arqum Hashmi, Shunsuke Yamada, Atsushi Yamada +2
Linear and nonlinear optical response of WSe monolayer is investigated by two-dimensional Maxwell plus time-dependent density functional theory with spin-orbit interaction. B…
Valley polarization control in WSe2 monolayer by a single-cycle laser pulse
Arqum Hashmi, Shunsuke Yamada, Atsushi Yamada +2
Abstract The valley degree of freedom in two-dimensional materials provides an opportunity to extend the functionalities of valleytronics devices. Very short valley lifetimes deman…
High order harmonic generation in semiconductors driven at near- and mid-IR wavelengths
David Freeman, Shunsuke Yamada, Atsushi Yamada +2
We study high order harmonics generation (HHG) in crystalline silicon and diamond subjected to near and mid-infrared laser pulses. We employ time-dependent density functional theor…
