‘Self-assembly and crystallisation in simple models of colloidal systems’

by Robert Jack,
Department of Physics, University of Bath, Bath, UK.

Rob JackAbstract:

Experiments on colloids are attractive as a route towards new self-assembled materials, and as models within which we can investigate general principles of self-assembly.  One typically aims to design a colloidal system such that a particular ordered state minimises the free energy, in which case one may hope that the colloid will spontaneously self-assemble into this state.  In practice, this process often fails, due to kinetic trapping — successful self-assembly typically requires the system to be designed such that there is an efficient dynamical pathway into the ordered state [1].

In this talk, I will present some recent computational results on self-assembly in model colloids, including characterisation of the effective interactions among anisotropic particles [2]…
