Comparison of experimental response with corresponding hypothetical free energy. Top panel: iIllustration of the possible experimental responses of a material upon exerting a positive mechanical pressure17,18,19,20,21. Bottom panel: hypothetical Helmholtz free energy F NT (V) and mechanical equation of state P NT (V), with N the number of particles and T the temperature, in terms of the volume. Shaded areas correspond to mechanically unstable regions
