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…

Probing ultrafast spin-relaxation and precession dynamics in a cuprate Mott insulator with 7-fs optical pulses
T. Miyamoto, Y. Matsui, T. Terashige +10
A charge excitation in a two-dimensional Mott insulator is strongly coupled with the surrounding spins, which is observed as magnetic-polaron formations of doped carriers and a mag…
