Directional solidification in thin samples of a eutectic alloy CBr4-C2Cl6. The solid is two-phase, composed of two different crystalline phases α and β. Diffusive dynamics are at the origin of the periodic alternation of...

  “Faceton”, or faceted solitary wave, in directional solidification in a thin sample of a mesomorphic molecule (denoted CCH4) exhibiting a nematic-smectic B transition. Smectic B is a “plastic crystal” phase with a lamellar...

Directional solidification in “thick” samples (typically 0.5 mm thick) of CBr4-C2Cl6 and succinonitrile-camphor alloys of concentrations inside the eutectic plateau. The solid is two-phased, composed of two different crystalline phases α and β. Diffusive...
