Book excerpt: We observe that the system trajectory on the free energy landscape is multi-dimensional and cannot be reduced to motion along a one-dimensional path on this surface. In order to elucidate the collective dynamics of the multiple degrees of freedom, the most likely path is identified on the free energy landscapes. Since the majority of natural and artificial surfactants are ionic, we also study the effects of electrostatic interactions on self-assembly of ionic surfactants. By solving the Poisson equation, it is shown that electrostatic potentials effectively increase (decrease) energy barriers of the addition (removal) of a surfactant molecule to (from) a micelle. It is anticipated that the approaches discussed in this study can be extended to investigation of more complex dynamic processes in amphiphilic systems.
