Abstract: | We consider the structure and properties of various topological defects that can occur in smectic C* liquid crystals. The
polarization field associated with disclinations, the effect of incommensuration on the structure of dispirations, some interesting
situations in the interaction between dispiration and disclination and between dispirations themselves have been discussed
in detail. The properties of cholesteric type disclinations and a possible model for the core structure of a wedge disclination
have also been dealt with.
The author felicitates Prof. D S Kothari on his eightieth birthday and dedicates this paper to him on this occasion. |
