  • We study tagged particle diffusion at large packing fractions, for a model of particles interacting with a generalized Lennard-Jones 2n–n potential, with large n. The resulting short range potential mimics interactions in colloidal systems. In agreement with previous calculations for short range potentials, we observe a diffusivity maximum as a function of temperature at constant density. By studying the temperature dependence of the configurational entropy—which we evaluate with two different… CONTINUE READING
