Uncovering Collective Modes Underlying the Giant Dielectric Response of Ferroelectric Nematic Liquid Crystals
Kazuma Nakajima, Hirokazu Kamifuji, Masanori Ozaki +2
Ferroelectric nematic liquid crystals (FNLCs) are polar fluids in which spontaneous polarization coexists with nematic orientational order, giving rise to unusual dielectric and el…
Evaluation of nonlinear optical coefficients in uniformly aligned dioxane-based ferroelectric nematic liquid crystals using second harmonic generation
Hirokazu Kamifuji, Jigen Furukawa, Kazuma Nakajima +3
Ferroelectric nematic liquid crystals (FNLCs) are promising soft platforms for nonlinear optics, but quantitative determination of their second-order nonlinear optical coefficients…
Geometry-Driven Polarization Control in Ferroelectric Nematic Liquid Crystals
Kazuma Nakajima, Hirokazu Kamifuji, Hirotsugu Kikuchi +2
Ferroelectric nematic liquid crystals (FNLCs) combine fluidity with spontaneous polarization, offering promising avenues for flexible electromechanical systems. Here, we demonstrat…
Ferroelectric Smectic C Liquid Crystal Phase with Spontaneous Polarization in the Direction of the Director
Hirotsugu Kikuchi, Hiroya Nishikawa, Hiroyuki Matsukizono +4
In our previous study, we demonstrated the existence of an unidentified ferroelectric smectic phase in the low-temperature region of the ferroelectric smectic A phase, where the la…
