D. Jones, M. Nakata, N. A. Clark, D. M. Walba, W. Weissflog, K. Fodor-Csorba, J. Watanabe, V. Novotna, and V. Hamplova<br/>We report a generalized scenario for the formation of modulated smectic phases of bent-core molecules based on locally ferroelectric layering and spontaneous splay of the polarization. Twelve phases are proposed, distinguished by neighboring splay stripes with either syn- or antiorder of the polariz...<br/>[Phys. Rev. E 77, 021703] Published Fri Feb 08, 2008 D. A. Coleman, C. D.

Warner<br/>The elastic response of a smectic- C elastomer to three deformations, namely imposed λ_{xx} , λ_{xz} , and λ_{zz} , has been modeled using a nonlinear theory of a nematic elastomer with embedded smectic layers, and with the director tilt (in the x direction) at a fixed angle with respect to the s...<br/>[Phys.

For all of the rod aspect ratios and area fractions studied, we find that confinement increases the degree of nematic ordering over the ...<br/>[Phys. Rev.

We report previously unexplored field-induced changes in the structures of some frustrated liquid crystal phases and describe them theoretically.
