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…

Transformation of polar nematic phases in the presence of electric field
A. V. Emelyanenko, V. Yu. Rudyak, F. Araoka +2
Only a few years have passed since discovery of polar nematics, and now they are becoming the most actively studied liquid crystal materials. Despite numerous breakthrough findings…
