(A) Polynomial fit (green curve) of the density dependence of the excess chemical potential (calculated by FMAP/BAR, shown as red crosses) at T = 0.65. (B) The full chemical potential, after adding the ideal part. A van der Waals loop, characterized by a decrease in μ with increasing ρ in the mid-range ρ, is present. The red horizontal line crosses the van der Waals loop with equal areas enclosed above and below. The height of this line corresponds to the chemical potential at phase coexistence, while the low and high ρ values where the red line intersects the green curve are the densities of the gas and liquid phases, respectively.
