リエントラント液晶相の出現機構 II

抄録

Reentrant liquid crystals are low ordered phases, which reappear at lower temperatures than that of higher ordered phases. The possibility of reentrant liquid crystals appearing when the volume is kept constant is investigated, using the same interaction among all molecules. The method of canonical hydrostatic molecular dynamics simulation is used for this purpose. Canonical hydrostatic simulation results are compared with simulation results of isobaric-isothermal ensemble. Reentrant smectic A and hexatic smectic B phases appear in several model systems. Elastic instabilities and elastic oscillations in these systems are reported.
