Dynamical field theories for biaxial liquid crystals
Anouar El Moumane, René Wittmann, Hartmut Löwen +1
Phase field crystal (PFC) models constitute central tools for a microscopic understanding of the dynamics of complex systems in soft matter physics. They have found widespread appl…
A Hitchhiker's Guide To Active Motion
Tobias Plasczyk, Paul A. Monderkamp, Hartmut Löwen +1
Intelligent decisions in response to external informative input can allow organisms to achieve their biological goals while spending very little of their own resources. In this pap…
Confined active particles with spatially dependent Lorentz force: an odd twist to the "best Fokker-Planck approximation"
René Wittmann, Iman Abdoli, Abhinav Sharma +1
We derive a version of the so-called "best Fokker-Planck approximation" (BFPA) to describe the spatial properties of interacting active Ornstein-Uhlenbeck particles (AOUPs) in arbi…
Layer topology of smectic grain boundaries
René Wittmann
Grain boundaries in extremely confined colloidal smectics possess a topological fine structure with coexisting nematic and tetratic symmetry of the director field. An alternative w…
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…
