We have systematically investigated the optical conductivity spectra of La$_{2-2x}$Sr$_{1+2x}$Mn$_{2}$O$_{7}$ ($0.3 \leqslant x \leqslant 0.5$). We find that just above the magnetic ordering temperatures, the optical gap shows an enhancement up to $\

We calculated the scalar wave scattering by an infinitely long circular cylinder on or near a planar substrate. Our calculation is based on a rigorous theoretical solution. We present the angular distributions of the scattered and the transmitted wav

We report numerical simulation results based on rigorous analytic solutions of scalar wave scattering caused by a cylinder buried in a planar substrate. As there are multiple interactions between the planar substrate and the cylinder, theoretical sol

We calculated the infrared conductivity spectrum of orbitally ordered LaMnO$_3$ in phonon frequency and overtone frequency ranges. We considered orbital exchange, Jahn-Teller electron-phonon coupling, and phonon--phonon coupling. The fundamental exci

We propose an excitation-probe measurement method utilizing entangled photon pulses. The excitation-probe signal is dominated by stimulated Raman scattering as well as two-photon absorption when the time delay between the excitation pulse and the pro

We measured photon absorption in dielectric media and proposed the photon-version Beer-Lambert's law to quantify the absorption. We used a Hong-Ou-Mandel interferometer and 810 nm twin-photons. We found that the depth ratio of the null point in the i

We measured time- and frequency-resolved phase changes owing to two-photon absorption induced by ultrashort (10 fs) pulses transmitted through a transparent material (ZnSe crystal), using femtosecond two-photon phase change spectroscopy. The maximal
