A critical assessment of the experimental investigations concerning reentrant phase transitions in liquid crystals is made and the factors which impede its proper understanding are identified. A survey is given of existing computer simulation studies of the isotropic to nematic transition, the nematic to...
Isotropic to smectic-C phase transition in liquid-crystalline elastomers A phenomenological model is developed to describe the isotropic-smectic-C phase transition in liquid-crystalline side-chain elastomers. We analyze the infl... Mukherjee,K Prabir - 《Journal of Chemical Physics》 被引量: 7发表...

By considering the twisting power, the ferrielectric phase was found to be composed of ferroelectric and antiferroelectric structures in the ratio of 3:7. The finite induced CD signal in SmC* and SmA in the vicinity of the transition point suggests the helical structure in these phases. 展开 ...
The method consists of calculating differences in the electrostatic free energies of charging and in the water-hydrocarbon interaction free energies for these two liquid-crystalline structures. There is notable success in describing the transition between the two forms as well as in the following ...
Novel liquid-crystal phase-transition behavior at the chiral nematic-smectic-A-smectic-C point New phenomenology of the chiral nematic (N), smectic-A (A), ferroelectric smectic-C (C) point (NAC) is reported in a binary mixture of two chiral component... DS Parmar,NA Clark,DM Walba,......
The stability of nematic and smectic order in clusters of spherocylinders is examined via Monte Carlo simulations. A discontinuous isotropic-nematic transition is observed as the cluster size is varied through N=35. A continuous transition to smectic A order takes place from N=55 to N=200. The...
