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 \…
Electron spill-out effect on third-order optical nonlinearity of metallic nanostructure
Takashi Takeuchi, Kazuhiro Yabana
Over the last three decades, plasmonics using metallic nanostructures has become central to nanophotonics research. Recently, its targets have been extended to nonlinear optical ph…
Infrared-Shielding of Plasmonic Random Metasurface Constructed by Cesium-Doped Tungsten Bronze
Tomohiro Yoshida, Takashi Takeuchi, Kazuhiro Yabana
The heat-shielding properties of random metasurface, composed of spherical or spheroidal nanoparticles with random displacements and/or random deformation, were theoretically inves…
First-principles method for nonlinear light propagation at oblique incidence
Mitsuharu Uemoto, Kazuhiro Yabana
We have developed a computational method to describe the nonlinear light propagation of an intense and ultrashort pulse at oblique incidence on a flat surface. In the method, coupl…
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…
Numerical scheme for nonlinear optical response of metallic nanostructure: Quantum hydrodynamic theory solved by adopting effective Schrödinger equation
Takashi Takeuchi, Kazuhiro Yabana
Quantum hydrodynamic theory (QHT) can describe some of the characteristic features of quantum electron dynamics that appear in metallic nanostructures, such as spatial nonlocality,…
