The pair potential of colloidal stars
F. Huang, K. Addas, A. Ward +5
We report on the construction of colloidal stars: 1 micrometer polystyrene beads grafted with a dense brush of 1 micrometer long and 10 nm wide semi-flexible filamentous viruses. T…
Enhanced stability of tetratic phase due to clustering
Yuri Martinez-Raton, Enrique Velasco
We show that the relative stability of the nematic tetratic phase with respect to the usual uniaxial nematic phase can be greatly enhanced by clustering effects. Two--dimensional r…
Biaxial nematic and smectic phases of parallel particles with different cross sections
Yuri Martinez-Raton, Szabolcs Varga, Enrique Velasco
We have calculated the phase diagrams of one--component fluids made of five types of biaxial particles differing in their cross sections. The orientation of the principal particle…
Non-uniform liquid--crystalline phases of parallel hard rod-shaped particles: From ellipsoids to cylinders
Yuri Martinez-Raton, Enrique Velasco
In this article we consider systems of parallel hard {\it superellipsoids}, which can be viewed as a possible interpolation between ellipsoids of revolution and cylinders. Superell…
Demixing and orientational ordering in mixtures of rectangular particles
D. de las Heras, Y. Martinez-Raton, E. Velasco
Using scaled-particle theory for binary mixtures of two-dimensional hard particles with rotational freedom, we analyse the stability of nematic phases and the demixing phase behavi…
