作为约束量子动力学的经典动力学

Classical Dynamics as Constrained Quantum Dynamics

Stephen D. Bartlett, David J. Rowe

摘要:

我们证明了代数模型的量子化隐含了它的经典力学。定义了一个代数模型,并给出了相应的经典和量子实现的频谱生成代数。然后通过将代数模型的量子动力学约束到适当的相干态流形上来获得经典的运动方程。对于相干态流形不是辛的情形,证明了存在到经典相空间的自然投影。这些结果与扩展的例子不对称的顶部。

英文摘要:

We show that the classical mechanics of an algebraic model are implied by its quantizations. An algebraic model is defined, and the corresponding classical and quantum realizations are given in terms of a spectrum generating algebra. Classical equations of motion are then obtained by constraining the quantal dynamics of an algebraic model to an appropriate coherent state manifold. For the cases where the coherent state manifold is not symplectic, it is shown that there exist natural projections onto classical phase spaces. These results are illustrated with the extended example of an asymmetric top.
