Applets  2DDipoles 
2DDipoles This is an applet showing the selfassembly of twodimensional dipolar particles. Dipoles at not too high temperatures selfassemble 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 attempt we 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.
