Density profile obtained from the square gradient model for different total mass of the system.
(a) Size of the bubble as a function of the total mass obtained from: SG theory (“profile SG+vdW,” solid red line); MBM assuming ideal gas and incompressible liquid (“MBM Kelvin,” dotted line); MBM with ideal gas and vdW liquid (“MBM IG+vdW,” triangles). The unstable branch of “MBM” solution is indicated with black dots. (b) Zoom of the region where the stable bubble disappears. The dashed vertical line indicates value of the mass corresponding to the equilibrium density of the liquid. The R in the caption stands for R ρ and R σ in case of the results from SG theory and MBM, respectively.
Schematic illustration of the “modified bubble model” (MBM).
(a) Chemical potential excess of the system as a function of the total mass from SG profile and from MBM. Unstable part of MBM solution is indicated by black dots. (b) Pressure inside the bubble and the surrounding liquid as a function of the total mass from MBM. Unstable part of MBM solution is indicated by black dots and crosses. Dashed vertical line indicates the value of the mass corresponding to the equilibrium density of the liquid.
