文摘The pressure versus temperature phase diagram of a shoulder-like potential is exactly computed in one system of particles interacting through a multiscale dimension. The N-shoulder potential exhibits N density anomaly regions in the phase diagram if the length scales can be connected by a convex curve The result is analyzed in terms of the convexity of the Gibbs free energy.
