title: Vapor-liquid coexistence in 2D square-well fluid with variable range of attraction: Monte Carlo simulation study.
abstract: Monte Carlo simulation study of the vapor-liquid coexistence in two-dimensional square-well fluid with 12 different values of the attraction shell width are reported. The densities of coexisting vapor and liquid phases as well as the coexisting chemical potentials for each simulated system are determined by means of hyperparallel tempering and histogram reweighting technique, while the location of critical point was tuned by means of the finite size scaling analysis. By studying dependence of the critical point parameters on the attraction shell width, we found that critical point temperature and critical point chemical potential both are changing monotonically while the critical point density oscillates, exhibiting higher or lower values depending on the particular width of the attraction shell.
