Calculation of correlation lengths in 2D Lennard-Jones fluids

vanyasimkin@gmail.com Abstract. The process of spinodal decomposition in two-dimensional system that was ob-tained by molecular dynamics simulation has been analysed using the correlation of reciprocal areas of the Voronoi cells. Correlation lengths dependence on the temperature and the critical exponent of the LJ12-6 system in the fluctuation region by the general renormalization group (RG) framework were calculated. We showed the agreement of the calculated critical exponent nu with both experiments and theory. The proposed methodology for correlations of the recip-rocal areas of the Voronoi cells is well applicable in the experiments with 2D colloidal systems.
