Abstract :

[en] Liquid crystals (LCs) have attracted enormous interest because of the variety of their phases and richness of their applications. Here, we revisit a selection of recent results that highlight the interplay between general physical symmetries, confinements (induced by solid interfaces),and microfluidic environments that reveal a range of intriguing phenomena. We start the chapter with recent results on nematic reentrancy under confinement to nanoscopic scales. Thereafter, we focus on the complex interplay of confinement and surface anchoring conditions that engenders topological defect structures in both nematics and cholesterics. We review how hydrodynamic flow interacts with the LC director,deforms topological defect lines, and ushers in a surprising behavior:low Reynolds number cavitation. Finally, we showcase recent results on the complex interaction between colloidal inclusions embedded in flowing LCs.
