Biaxial nematic order in fundamental measure theory
Anouar El Moumane, Michael te Vrugt, Hartmut Löwen +1
Liquid crystals consisting of biaxial particles can exhibit a much richer phase behavior than their uniaxial counterparts. Usually, one has to rely on simulation results to underst…
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…
The Parental Active Model: a unifying stochastic description of self-propulsion
Lorenzo Caprini, Alexander Ralf Sprenger, Hartmut Löwen +1
We propose a new overarching model for self-propelled particles that flexibly generates a full family of "descendants". The general dynamics introduced in this paper, which we deno…
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…
Active Ornstein-Uhlenbeck model for self-propelled particles with inertia
G. H. Philipp Nguyen, René Wittmann, Hartmut Löwen
Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized…
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…
