Emerging electro-optic molecular crystals for optoelectronic integration
Keishi Sunami, Sachio Horiuchi, Yoriko Sonoda +5
The rapid advancement of communication technology necessitates the development of hybrid optical modulators that integrate silicon photonics with electro-optic (EO) materials to en…
NMR verification of Dirac nodal lines in a single-component molecular conductor
Takahiko Sekine, Keishi Sunami, Takumi Hatamura +6
The Dirac nodal line (DNL) is a novel form of massless Dirac fermions that reside along lines in momentum space. Here, we verify genuine DNLs in the molecular material, [Ni(dmdt)$_…
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…
