Resilient quantum electron microscopy
Hiroshi Okamoto
We investigate the fundamental limit of biological quantum electron microscopy, which is designed to go beyond the shot noise limit. Inelastic scattering is expected to be the main…
Biexciton in one-dimensional Mott insulators
T. Miyamoto, T. Kakizaki, T. Terashige +10
Mott insulators sometimes show dramatic changes in their electronic states after photoirradiation, as indicated by photoinduced Mott-insulator-to-metal transition. In the photoexci…
Strong terahertz radiation via rapid polarization reduction in photoinduced ionic-to-neutral transition of tetrathiafulvalene-p-chloranil
Yuto Kinoshita, Noriaki Kida, Yusuke Magasaki +4
Terahertz lights are usually generated through the optical rectification process within a femtosecond laser pulse in non-centrosymmetric materials. Here, we report a new generation…
Narrowband terahertz radiation by an impulsive stimulated Raman scattering in an above-room-temperature organic ferroelectric benzimidazole
M. Sotome, N. Kida, S. Horiuchi +1
We observe a terahertz radiation from a hydrogen-bonded organic molecular ferroelectric 5,6-dichloro-2-methylbenzimidazole excited by a femtosecond laser pulse at room temperature.…
Terahertz radiation by subpicosecond spin-polarized photocurrent originating from Dirac electrons in a Rashba-type polar semiconductor
Yuto Kinoshita, Noriaki Kida, Tatsuya Miyamoto +3
The spin-splitting energy bands induced by the relativistic spin-orbit interaction in solids provide a new opportunity to manipulate the spin-polarized electrons on the sub-picosec…
Separation of Charge Instability and Lattice Symmetry Breaking in an Organic Ferroelectric
Ryosuke Takehara, Keishi Sunam, Fumitatsu Iwase +5
We investigate the charge and lattice states in a quasi-one-dimensional organic ferroelectric material, TTF-QCl, under pressures of up to 35 kbar by nuclear quadrupole resona…
