摘要
It is shown that transient spin-spin correlations in a one-dimensional spin S >> 1 chain can be enhanced for initially factorized and individually squeezed spin states. Such correlation transfer from "internal" to "external" degrees of freedom can be well described by using a semiclassical phase-space approach.
