H. Pleiner et Hr. Brand, NONLINEAR HYDRODYNAMICS OF STRONGLY DEFORMED SMECTIC-C AND C-ASTERISKLIQUID-CRYSTALS, Ferroelectrics (Print), 214(1-2), 1998, pp. 693-700
The statics and dynamics of smectic C (and C) liquid crystals has bee
n a long-standing topic for investigations. All the previous descripti
ons, how-ever, have been restricted in some sense. Either the theories
were linear, or flat layers were assumed, or the layer thickness was
taken to be constant, or only statics was considered, or the descripti
on (in the chiral case) included terms not compatible with layering. H
ere we will give a nonlinear hydrodynamic theory, which applies to str
ongly curved layers, non-flat 'ground' states, strongly compressed lay
ers as well as strongly deformed director orientations. Some discrepan
cies between previous theories are resolved.
