The concept of “re- interpret at ing” (mapping) the parameters of the Ising model in terms of (onto) effective pair-, triplet- and so on interactions, opens up new possibilities in computational solid state physics. In particular in connection with the Coherent Potential Approximation (CPA), which describes perfectly statistical chemical disorder, it appears that now a combination of methods is available that allows to describe with one and the same approach ground state properties such as transport properties, as well as uniquely determined parameters for statistical mechanics. One might as well add, that within the limitations of the local density approximation also an essentially parameterfree theoretical spectroscopy (e.g. XPS, XES or AES) for disordered or partially ordered systems is at hand.
