摘要:
We discuss the difficulties of using quasiclassical methods to describe two time correlation functions for spin systems. We show that there is an inherent difficulty in deriving quasiclassical equations of motion. In particular, we show that for the two spin case the equivalents of the Heisenberg operators S∼j(t) satisfy equations which deviate dramatically from what one would expect for classical equations.
