Colloidal smectics in button-like confinements: experiment and theory
René Wittmann, Paul A. Monderkamp, Jingmin Xia +5
Liquid crystals can self-organize into a layered smectic phase. While the smectic layers are typically straight forming a lamellar pattern in bulk, external confinement may drastic…
Topology of orientational defects in confined smectic liquid crystals
Paul A. Monderkamp, René Wittmann, Louis B. G. Cortes +3
We propose a general formalism to characterize orientational frustration of smectic liquid crystals in confinement by interpreting the emerging networks of grain boundaries as obje…
Particle-resolved topological defects of smectic colloidal liquid crystals in extreme confinement
René Wittmann, Louis B. G. Cortes, Hartmut Löwen +1
Confined samples of liquid crystals are characterized by a variety of topological defects and can be exposed to external constraints such as extreme confinements with nontrivial to…
