Dipoles

The applet shows the self-assembly of two-dimensional dipolar particles. Dipoles at not too high temperatures self-assemble into chain like structures due to their interactions.

The applet will start by clicking the button Start. It will initialize a canonical Monte Carlo simulation, where in each step we attempt to displace and change the orientation of a randomly chosen dipole. The attempt is accepted or rejected by the traditional Metropolis criterion. Our system is composed of N dipoles with temperature T and dipole moment μ such that the dipoles will form chains. Occasionally, the ends of a chain may come together and form a ring. Additionally, one can introduce an external field, H*, to align the structures to a certain direction.
