Fate of a soliton matter upon symmetry-breaking ferroelectric order
K. Sunami, R. Takehara, A. Katougi +6
In a one-dimensional (1D) system with degenerate ground states, their domain boundaries, dubbed solitons, emerge as topological excitations often carrying unconventional charges an…
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…
Long-term stabilization of carrier envelope phases of mid-infrared pulses for the precise detection of phase-sensitive responses to electromagnetic waves
T. Yamakawa, N. Sono, T. Kitao +4
We report a newly designed mid-infrared-pump visible-probe measurement system, which can measure phase-sensitive responses to a mid-infrared pulse along the oscillating electromagn…
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…
Photoexcitation of a polarization-inverted domain from the charge-ordered ferroelectric ground state of (TMTTF)PF
T. Yamaguchi, K. Asada, H. Yamakawa +5
We theoretically revealed that a weak photoexcitation achieves the electric polarization-inversion with approximately of all the charges, which was interpreted as a superimp…
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…
