Interparticle potential barriers in soft matter systems.
We discuss how a system of particles with bounded interaction potentials responds to increased densities. In particular we elaborate the ability of a system to form potential barriers between the particles, to allow a so called cluster formation. These theoretical considerations are complemented by computer simulations that allow us to observe the onset of clustering at low particle densities. We discuss the simulation results with regard to the presence of potential barriers and establish a formulation to explain the effect of potential barriers by the use of the Fourier transform of the potential function.
