Tracking ultrafast change of multiterahertz broadband response functions in a photoexcited Dirac semimetal CdAs thin film
Natsuki Kanda, Yuta Murotani, Takuya Matsuda +5
The electromagnetic response of Dirac semimetals in the infrared and terahertz frequency ranges is attracting growing interest for potential applications in optoelectronics and non…
Room-Temperature Terahertz Anomalous Hall Effect in Weyl Antiferromagnet MnSn Thin Films
Takuya Matsuda, Natsuki Kanda, Tomoya Higo +3
Antiferromagnetic spin motion at terahertz (THz) frequencies attracts growing interests for fast spintronics, however their smaller responses to external field inhibit device appli…
Efficient Terahertz Harmonic Generation with Coherent Acceleration of Electrons in the Dirac Semimetal Cd3As2
Bing Cheng, Natsuki Kanda, Tatsuhiko N. Ikeda +7
We report strong terahertz (~10^12 Hz) high harmonic generation in thin films of Cd3As2, a three-dimensional Dirac semimetal at room temperature. The third harmonics is detectable…
Proposal of highly efficient photoemitter with strong photon-harvesting capability and exciton superradiance
Takuya Matsuda, Hajime Ishihara
We propose a system of highly efficient photoemitters comprising metal-dielectric (plasmonic-excitonic) multilayered structures. In the proposed structure, the absorption in the ex…
Up-converted photoluminescence induced by radiative coupling between excitons
Takuya Matsuda, Nobuhiko Yokoshi, Hajime Ishihara
We propose an unconventional scheme of photoluminescence in a semiconductor thin film, where the nonlocal correlation between an excitonic wave and a light wave prominently enhance…
