Static and hydrodynamic periodic structures induced by AC electric fields in the antiferroelectric SmZA phase
K. S. Krishnamurthy, S. Krishna Prasad, D. S. Shankar Rao +4
We report the effect of AC electric fields in the range of 0.1-300 kHz on planar antiferroelectric SmZA layers of DIO. Significant results are (a) primary bifurcation into a quasis…
A novel modulated phase of liquid crystals: Covariant elasticity in the context of soft, achiral smectic-C materials
P. R. Venkatramanan, Yashodhan Hatwalne, N. V. Madhusudana
Ginzburg-Landau-de Gennes -type covariant theories are extensively used in connection with twist grain boundary (TGB) phases of chiral smectogens. We analyze the stability conditio…
Escape configuration lattice near the nematic-isotropic transition: Tilt analogue of blue phases
Buddhapriya Chakrabarti, Yashodhan Hatwalne, N. V. Madhusudana
We predict the possible existence of a new phase of liquid crystals near the nematic-isotropic () transition. This phase is an achiral, tilt-analogue of the blue phase and is…
The Cone Phase of Liquid Crystals: Triangular Lattice of Double-Tilt Cylinders
Yashodhan Hatwalne, N. V. Madhusudana
We predict the existence of a new defect-lattice phase near the nematic - smectic-C (NC) transition. This tilt- analogue of the blue phase is a lattice of double-tilt cylinders. We…
A 3 - dimensionally modulated structure in a chiral smectic-C liquid crystal
P. A. Pramod, R. Pratibha, N. V. Madhusudana
We report the discovery of a new Twist Grain Boundary phase. This phase is characterised by a 2-dimensional undulation of the smectic C* like blocks in the form of a square lattice…
