论文摘要
我们参考众所周知的半经典模型，其中量子的自由度与古典模型相互作用。我们表明，在经典限制下，可以通过纯态密度矩阵来表示经典结果（例如，经典混乱）。
We work with reference to a well-known semiclassical model, in which quantum degrees of freedom interact with classical ones. We show that, in the classical limit, it is possible to represent classical results (e.g., classical chaos) by means a pure-state density matrix.
