Colloidal Aggregation

We study self-assembly on a spherical surface of a model for a binary mixture of amphiphilic dimers in the presence of guest particles via Monte Carlo (MC) computer simulation. All particles had a hard core, but one monomer of the dimer also interacted with the guest particle by means of a short-range attractive potential. We observed the formation of aggregates of various shapes as a function of the composition of the mixture and of the size of guest particles. Our MC simulations are a further step towards a microscopic understanding of experiments on colloidal aggregation over curved surfaces, such as oil droplets.

Shaped Nanoparticles

Understanding how nanoparticles self-assemble into specific structures is important in biology. The self-assembly structures of disc-shaped nanoparticles are investigated using Gay Berne potential. Through the simulated annealing Monte Carlo simulation underNVTcondition, we found that various nanostructures such as nematic phase and isotropic phase are discovered. The formation mechanism of these novel nanostructures is discussed.

The hole-hole correlation function in the 2D Hubbard model is investigated in the low doping regime both via Monte Carlo simulations for U=4 and Lanczos diagonalization on a 16 site cluster for very large U. The results are compared with available theoretical predictions for the strong coupling limit. There is a clear short range repulsion, but no signature of hole-hole attraction is found in either case. At U=4 correlations are still remarkably weak-coupling-like. For large U, they become rather similar to those of hard core bosons.
