Description of molecular chirality and its analysis with high harmonic generation
Akihito Kato, Nobuhiko Yokoshi
To clarify the microscopic origin of chirality-induced optical effect, we develop an analytical method that extracts the chiral part of the Hamiltonian of molecular electronic stat…
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…
Theoretical Analysis of Optically Selective Imaging in Photoinduced Force Microscopy
Hidemasa Yamane, Junsuke Yamanishi, Nobuhiko Yokoshi +2
We present a theoretical study of the measurements of photoinduced force microscopy (PiFM) for composite molecular systems. Using the discrete dipole approximation, we calculate th…
Weak-Light Nonlinearity Using a Dark State in Coupled Quantum Dots
Nobuhiko Yokoshi, Hajime Ishihara
We propose a scheme to induce weak-light nonlinearity in a double quantum dot. The scheme positively utilizes locality and dissipation of an external auxiliary system. As a plausib…
Synchronization dynamics in a designed open system
Nobuhiko Yokoshi, Kazuki Odagiri, Akira Ishikawa +1
We theoretically propose a unifying expression for synchronization dynamics between two-level constituents. Although synchronization phenomena require some substantial mediators, t…
Two-photon up-conversion affected by inter-molecule correlations near metallic nanostructure
Yoshiki Osaka, Nobuhiko Yokoshi, Hajime Ishihara
We investigate an efficient two-photon up-conversion process in more than one molecule coupled to an optical antenna. In the previous work [Y. Osaka et al., PRL 112, 133601 (2014)]…
