Liquids and solids with (primarily) van der Waals bonds or metallic bonds - or weak Coulomb forces - have "isomorphs" in their thermodynamic phase diagram, whereas covalently bonded systems or systems with hydrogen-bonds do not. An isomorph is a configurational adiabat along which structure and dynamics are invariant in reduced units. We summarize the evidence for this novel picture of condensed matter and demonstrate how it all follows in a quite straightforward way from the former systems' "hidden scale invariance", as shown recently [1].
