Self-assembly and entropic effects in pear-shaped colloid systems: I. Shape sensitivity of bilayer phases in colloidal pear-shaped particle systems
Philipp W. A. Schönhöfer, Matthieu Marechal, Douglas J. Cleaver +1
The role of particle shape in self-assembly processes is a double-edged sword. On the one hand, particle shape and particle elongation are often considered the most fundamental det…
Self-assembly and entropic effects in pear-shaped colloid systems: II. Depletion attraction of pear-shaped particles in a hard sphere solvent
Philipp W. A. Schönhöfer, Matthieu Marechal, Douglas J. Cleaver +1
We consider depletion effects of a pear-shaped colloidal particle in a hard-sphere solvent, for two different model realisations of the pear-shaped colloidal particle. The two mode…
Isotropic-nematic transition of self-propelled rods in three dimensions
Matthias C. Bott, Felix Winterhalter, Matthieu Marechal +3
Using overdamped Brownian dynamics simulations we investigate the isotropic-nematic (IN) transition of self-propelled rods in three spatial dimensions. For two well-known model sys…
Simulation of a Hard-Spherocylinder Liquid Crystal with the pe
Ellen Fischermeier, Dominik Bartuschat, Tobias Preclik +2
The pe physics engine is validated through the simulation of a liquid crystal model system consisting of hard spherocylinders. For this purpose we evaluate several characteristic p…
Dynamical States in Driven Colloidal Liquid Crystals
Ellen Fischermeier, Matthieu Marechal, Klaus Mecke
We study a model colloidal liquid crystal consisting of hard spherocylinders under the influence of an external aligning potential by Langevin dynamics simulation. The external fie…
Deriving fundamental measure theory from the virial series: Consistency with the zero-dimensional limit
Matthieu Marechal, Stephan Korden, Klaus Mecke
Fundamental measure theory (FMT) for hard particles has great potential for predicting the phase behavior of colloidal and nanometric shapes. The modern versions of FMT are usually…
Differently Shaped Hard Body Colloids in Confinement: From passive to active particles
Henricus H. Wensink, Hartmut Löwen, Matthieu Marechal +5
We review recent progress in the theoretical description of anisotropic hard colloidal particles. The shapes considered range from rods and dumbbells to rounded cubes, polyhedra an…
Rhombic preordering on a square substrate
T. Neuhaus, M. Marechal, M. Schmiedeberg +1
A competition of incommensurate symmetries occurs whenever a system is forced to conform to an ordering that is different from the intrinsically preferred structure of the system i…
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…
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…
Frustration of the isotropic-columnar phase transition of colloidal hard platelets by a transient cubatic phase
Matthieu Marechal, Alessandro Patti, Matthew Dennison +1
Using simulations and theory, we show that the cubatic phase is metastable for three model hard platelets. The locally favored structures of perpendicular particle stacks in the fl…
Vacancy-stabilized crystalline order in hard cubes
Frank Smallenburg, Laura Filion, Matthieu Marechal +1
We examine the effect of vacancies on the phase behavior and structure of systems consisting of hard cubes using event-driven molecular dynamics and Monte Carlo simulations. We fin…
Phase behavior and structure of colloidal bowl-shaped particles: simulations
Matthieu Marechal, Marjolein Dijkstra
We study the phase behavior of bowl-shaped particles using computer simulations. These particles were found experimentally to form a meta-stable worm-like fluid phase in which the…
