关于相干态随时间的演化
On the time evolution of coherent states
摘要
本文用密度矩阵方法研究了相干态在时间演化过程中仍保持为相干态的充要条件.证实Glauber条件是正确的,Kauo的非议是没有根据的,Glauber条件适用于相当一般形式的哈密顿量.
Abstract
By means of the density matrix method, the necessary and sufficient conditions for a coherent state to remain coherent at all times are discussed. It is shown that the conditions of Glauber are correct, the censure of Kano is groundless, and the conditions of Glauber are applicable for the Hamiltonian in quite general form.
