Team Permanent members: Emmanuelle Lacaze, Sébastien Royer PhD Students: Lamia Essaoui, Caterina Tosarelli, Xintao Zheng Liquid crystal topological defects are among condensed matter topological defects the easiest to control for a deep study of defect...

Team Permanent members: Emmanuelle Lacaze, Sébastien Royer, Michel Goldmann Liquid crystal topological defects are among condensed matter topological defects the easiest to control for a deep study of defect structure and properties. We know now...

Team Permanent member: Olivier Pluchery Molecules are self-assembled into monolayers on silicon surfaces with an extreme control so that we can avoid any oxidation of silicon, even at room pressure. We have especially studied...

Team Permanent member: Olivier Pluchery   Gold nanoparticles can be viewed as extra-small electrodes and help understand how electronic currents can be controlled at the smallest scale at complex interfaces. The unrivalled advantage of...

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...

Team Permanent members: Yves Borensztein, Sébastien Royer   The localized surface plasmon resonance (LSPR) in metallic nanoparticles (NPs) induces a strong enhancement of the electromagnetic field at the surface of the NPs. Consequently, monitoring...
