Lindemanns' criterion and the necessary condition for a melting curve maximum
Review articleOpen access

AbstractAssuming that the generalized Lindemann's criterion adequately describes the melting process, it is shown that the softening of a branch of the frequency spectrum with pressure is associated with the occurrence of fusion curve maximum as well as a negative melting slope. By characterizing the number of “soft” modes through 〈γ〉 and σ12, the average and approximate width of the mode gamma distribution of the solid, a qualitative as well as a quantitative condition for a fusion curve maximum can be established for a model potential.
