哈密顿量显含时间的玻色系统时间演变及厄密不变量

Time Evolution of A Boson System with Explicitly Time-dependent Hamiltonian and the Hermitian Invariant Operator

本文研究含时耦合玻色系统的时间演化，并且发现用适当选取的厄密不变量，不仅可得到系统量子态的时间演化封闭解，而且可得到时间演化正算符．本文利用时间演化算符讨论了含时耦合光场的相干性．

The time evolution of time dependent coupling Boson system is studied. A Proper bermitian invariant operator has been found to obtain not only closed formulas for the time evolution of the quantum states but also evolution operators for Boson systems. The time evolution operators have been used to investigate the coherence of time-dependent optical field.
