Quantum transport of topological spin solitonsin a one-dimensional organic ferroelectric
Shusaku Imajo, Atsushi Miyake, Ryosuke Kurihara +4
We report the dielectric, magnetic, and ultrasonic properties of a one-dimensional organic salt TTF-QBrI. These indicate that TTF-QBrI shows a ferroelectric spin-Peierls (F…
Enhanced lattice fluctuations prior to a nonmagnetic ferroelectric order in an ionic spin-chain system
Keishi Sunami, Tomohiro Baba, Kazuya Miyagawa +2
We investigated microscopic lattice states in the donor-acceptor ionic Mott insulator, TTF-BA, by Br-NQR spectroscopy to explore cross-correlated fluctuations between spin,…
Magnetic excitations in an ionic spin-chain system with a non-magnetic ferroelectric instability
K. Sunami, Y. Sakai, R. Takehara +4
Cross-correlation between magnetism and dielectric is expected to offer novel emergent phenomena. Here, magnetic excitations in the organic donor-acceptor spin-chain system, TTF-BA…
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…
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.…
