  "Conventional" scenario of metastable melting in ordinary substances in the
limit of zero temperature assumes that the melting curve reaches the matter
zero isotherm ("cold curve"). The same is true for standard variant of
one-component plasma model on rigid compensating background in both limits:
classical and "cold" quantum melting. The modified OCP on uniform, but
compressible background shows the completely different scenario of the
metastable melting closure. The remarkable feature of this scenario is that the
liquid freezing curve terminates at liquid spinodal curve of 1st-order liquid
gas phase transition, which takes place in this type of OCP models ("spinodal
decomposition").
