Phase diagram of colloidal hard superballs: from cubes via spheres to octahedra
Ran Ni, Anjan Prasad Gantapara, Joost de Graaf +2
The phase diagram of colloidal hard superballs, of which the shape interpolates between cubes and octahedra via spheres, is determined by free-energy calculations in Monte Carlo si…
Depletion-induced biaxial nematic states of boardlike particles
Simone Belli, Marjolein Dijkstra, René van Roij
With the aim of investigating the stability conditions of biaxial nematic liquid crystals, we study the effect of adding a non-adsorbing ideal depletant on the phase behavior of co…
Ion association in low-polarity solvents: comparisons between theory, simulation, and experiment
Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken +2
The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The spec…
Dense Regular Packings of Irregular Non-Convex Particles
Joost de Graaf, René van Roij, Marjolein Dijkstra
We present a new numerical scheme to study systems of non-convex, irregular, and punctured particles in an efficient manner. We employ this method to analyze regular packings of od…
Polydispersity stabilizes Biaxial Nematic Liquid Crystals
S. Belli, A. Patti, M. Dijkstra +1
Inspired by the observations of a remarkably stable biaxial nematic phase [E.v.d. Pol et al., Phys. Rev. Lett. 103, 258301 (2009)], we investigate the effect of size polydispersity…
Phase diagram and effective shape of semi-flexible colloidal rods and biopolymers
Matthew Dennison, Marjolein Dijkstra, Rene van Roij
We study suspensions of semi-flexible colloidal rods and biopolymers using an Onsager-type second-virial functional for a segmented-chain model. For suspensions of thin and thick f…
