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…
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…
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…
