Dissipation in monotonic and non-monotonic relaxation to equilibrium

Petersen, Charlotte; Evans, Denis; Williams, Stephen


Using molecular dynamics simulations, we study field free relaxation from a non-uniform initial density, monitored using both density distributions and the dissipation function. When this density gradient is applied to colour labelled particles, the density distribution decays to a sine curve of fundamental wavelength, which then decays conformally towards a uniform distribution. For conformal relaxation, the dissipation function is found to decay towards equilibrium monotonically, consistent...[Show more]
