Packing Confined Hard Spheres Denser with Adaptive Prism Phases
Erdal C. Oğuz, Matthieu Marechal, Fernando Ramiro-Manzano +4
We show that hard spheres confined between two parallel hard plates pack denser with periodic adaptive prismatic structures which are composed of alternating prisms of spheres. The…
Extended dynamical density functional theory for colloidal mixtures with temperature gradients
Raphael Wittkowski, Hartmut Löwen, Helmut R. Brand
In the past decade, classical dynamical density functional theory (DDFT) has been developed and widely applied to the Brownian dynamics of interacting colloidal particles. One of t…
Traveling and resting crystals in active systems
Andreas M. Menzel, Hartmut Löwen
A microscopic field theory for crystallization in active systems is proposed which unifies the phase-field-crystal model of freezing with the Toner-Tu theory for self-propelled par…
Meso-scale turbulence in living fluids
Henricus H. Wensink, Jörn Dunkel, Sebastian Heidenreich +4
Turbulence is ubiquitous, from oceanic currents to small-scale biological and quantum systems. Self-sustained turbulent motion in microbial suspensions presents an intriguing examp…
Phase-field-crystal models for condensed matter dynamics on atomic length and diffusive time scales: an overview
Heike Emmerich, Hartmut Löwen, Raphael Wittkowski +4
Here, we review the basic concepts and applications of the phase-field-crystal (PFC) method, which is one of the latest simulation methodologies in materials science for problems,…
Emergent states in dense systems of active rods: from swarming to turbulence
H. H. Wensink, H. Löwen
Dense suspensions of self-propelled rod-like particles exhibit a fascinating variety of non-equilibrium phenomena. By means of computer simulations of a minimal model for rigid sel…
Freezing of parallel hard cubes with rounded edges
Matthieu Marechal, Urs Zimmermann, Hartmut Löwen
The freezing transition in a classical three-dimensional system of parallel hard cubes with rounded edges is studied by computer simulation and fundamental-measure density function…
How to capture active particles
A. Kaiser, H. H. Wensink, H. Löwen
For many applications, it is important to catch collections of autonomously navigating microbes and man-made microswimmers in a controlled way. Here we propose an efficient trap to…
