摘要
利用两粒子相对坐标和总动量的共同本征态|η〉构成的连续变量纠缠态表象,推导了转动系统的Ehrenfest定理,从而说明了在满足某些近似的情况下,量子力学不但能够与经典物理完美自洽,而且利用量子力学的规律可以导出相应的经典物理规律.
The Generalized Ehrenfest theorem is deduced by using the entangled state representation, that is the common eigenstate of relative coordinate and general momentum of two particles. It is shown that not only quantum mechanics is self-consistent with classical physics, but also the corresponding classical physics law could be deduced by virtue of the quantum mechanics law.
