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…
Tunable Intracavity Coherent Up-conversion with Giant Nonlinearity in a Polar Fluidic Medium
Daichi Okada, Hiroya Nishikawa, Fumito Araoka
We demonstrate a novel microcavity-based photon up-conversion using second harmonic generation (SHG) from a polar nematic fluid media doped with a laser dye. The present idea is ba…
Emergent Ferroelectric Nematic and Heliconical Ferroelectric Nematic States in an Achiral "Straight" Polar Rod Mesogen
Hiroya Nishikawa, Daichi Okada, Dennis Kwaria +4
Ferroelectric nematic liquid crystals (NFLCs) are distinguished by their remarkable polarization characteristics and diverse physical phenomena, sparking significant interest and e…
