Proposed optomechanical systems based on luminescence-induced optical forces
Hideki Arahari, Sota Konishi, Kodai Takaoka +2
We propose an optomechanical system utilizing luminescence-induced optical forces (LIOFs). Anisotropic dielectric structures enhance the recoil force from the luminescence. The opt…
Functionalized high-speed magnon-polaritons resulting from the magnetic antenna effect
Kenta Kato, Tomohiro Yokoyama, Hajime Ishihara
Magnon-polaritons (MPs) refer to a light--magnon coupled state and can potentially act as information carriers, possibly enabling charge-free computation. However, the light--magno…
Nonlocal inelastic scattering of light: Enhanced and noiseless signals in remote-coupled optomechanical systems
Sho Tamaki, Tomohiro Yokoyama, Hajime Ishihara
The inelastic scatterings of matter systems, such as Raman scattering, contain rich information on mechanical vibrations like as resonant frequencies, which lead to various applica…
Comprehensive Microscopic Theory for Coupling of Longitudinal--Transverse Fields and Individual--Collective Excitations
Tomohiro Yokoyama, Masayuki Iio, Takashi Kinoshita +2
A plasmon is a collective excitation of electrons due to the Coulomb interaction. Both plasmons and single-particle excitations (SPEs) are eigenstates of bulk metallic systems and…
Rotation of optically bound particle assembly due to scattering induced spin-orbit coupling of light
Yukihiro Tao, Tomohiro Yokoyama, Hajime Ishihara
The optical binding of many particles has great potential to achieve the wide-area formation of a "crystal" of small materials. Unlike conventional optical binding, where the whole…
Twisted light-induced spin-spin interaction in a chiral helimagnet
Yutaro Goto, Hajime Ishihara, Nobuhiko Yokoshi
We theoretically investigate how the orbital angular momentum of light can affect a chiral magnetic order. Here, we consider a metallic chiral helimagnet, which is under stationary…
