Disclinations, dislocations and continuous defects: a reappraisal
Maurice Kleman, Jacques Friedel
Disclinations, first observed in mesomorphic phases, are relevant to a number of ill-ordered condensed matter media, with continuous symmetries or frustrated order. They also appea…
Imperfections in focal conic domains: the role of dislocations
M. Kleman, C. Meyer, Yu. A. Nastishin
It is usual to think of Focal Conic Domains (FCD) as perfect geometric constructions in which the layers are folded into Dupin cyclides, about an ellipse and a hyperbola that are c…
Helical Ribbons as Isometric Textures
M. -F. Achard, M. Kleman, Yu. A. Nastishin +1
Deformations that conserve the parallelism and the distances --between layers, in smectic phases; between columns, in columnar phases-- are commonplace in liquid crystals. The resu…
Textural Analysis of a Mesophase with Banana Shaped Molecules
Yu. A. Nastishin, M. F. Achard, H. T. Nguyen +1
Observed under the polarizing microscope, the B7bis phase in the banana compound D14F3 [J.P. Bedel et al, Liq. Cryst., 27, 1411 (2000)] displays two types of textures of defects, n…
