Plane photoacoustic wave generation in liquid water using irradiation of terahertz pulses
Masaaki Tsubouchi, Hiromichi Hoshina, Masaya Nagai +1
We demonstrate photoacoustic wave propagation with a plane wavefront in liquid water using a terahertz (THz) laser pulse. The THz light can effectively generate the photoacoustic w…
Ultrafast near infrared photoinduced absorption in a multiferroic single crystal of bismuth ferrite
Eiichi Matsubara, Takeshi Mochizuki, Masaya Nagai +2
We studied the ultrafast third-order optical nonlinearity in a single crystal of multiferroic bismuth ferrite (BiFeO3) in the near-infrared range of 0.5-1.0 eV, where the material…
Formation and decay of electron-hole droplets in diamond
J. H. Jiang, M. W. Wu, M. Nagai +1
We study the formation and decay of electron-hole droplets in diamonds at both low and high temperatures under different excitations by master equations. The calculation reveals th…
Study of the formation and decay of electron-hole plasma clusters in a direct-gap semiconductor CuCl
L. Jiang, M. W. Wu, M. Nagai +1
The master equation for the cluster-size distribution function is solved numerically to investigate the electron-hole droplet formation claimed to be discovered in the direct-gap C…
