Enhancement of valley selective excitation by a linearly polarized two-color laser pulse
Arqum Hashmi, Shunsuke Yamada, Kazuhiro Yabana +1
Here we proposed the valley selective excitations via a two-color (\ensuremathω + \ensuremath{2ω}) laser field, made by superimposing two linearly polarized pulses at frequencies \…
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…
Time-dependent density functional theory for interaction of ultrashort light pulse with thin materials
Shunsuke Yamada, Masashi Noda, Katsuyuki Nobusada +1
We present a comprehensive theoretical description for an irradiation of an ultrashort light pulse normally on thin materials based on first-principles time-dependent density funct…
