Discovery of transient topological crystalline order in optically driven SnSe
Masataka Mogi, Dongsung Choi, Kyoung Hun Oh +13
Ultrafast optical excitation provides a powerful route for accessing emergent quantum phases far from equilibrium, enabling transient light-induced phenomena such as magnetism, fer…
Excitonic optical spectra and energy structures in a one-dimensional Mott insulator demonstrated by applying a many-body Wannier functions method to a charge model
T. Yamaguchi, K. Iwano, T. Miyamoto +5
We have applied a many-body Wannier functions method to theoretically calculate an excitonic optical conductivity spectrum and energy structure in a one-dimensional (1D) Mott insul…
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…
Visualization of photogenerated metallic inhomogeneity in the insulating phase of PrCaMnO thin film using spatiotemporal terahertz radiation imaging
N. Kida, M. Tonouchi
Using a spatiotemporal terahertz radiation imaging technique, we visualize photogenerated metallic inhomogeneity in the charge-ordered insulating phase of PrCaMnO$_…
