Displacements, columnar phases

As for crystals, tire elasticity of smectic and columnar phases is analysed in tenns of displacements of tire lattice witli respect to the undistorted state, described by tire field u(r). This represents tire distortion of tire layers in a smectic phase and, tluis, u(r) is a one-dimensional vector (conventionally defined along z), whereas tire columnar phase is two dimensional, so tliat u(r) is also. The symmetry of a smectic A phase leads to an elastic free energy density of tire fonn [86]... [Pg.2558]

A simple derivation of tliis equation based on tire lowest-order derivative (curvature) of tire layer displacement field u(r) has been provided [87]. A similar expression can be obtained for a uniaxial columnar phase [20] (witli tire columns lying in tire z direction) ... [Pg.2558]
