量子力学中的含时微扰理论

Time-dependent Perturbation Theory in Quantum Mechanics

C. Y. Chen

摘要:

主要从实际计算的角度揭示了量子力学中标准含时微扰理论的困难,提出了一种新的准正则微扰理论。在新理论中,物理观测量的动力学,而不是波函数展开系数的动力学,制定规范不变性和对应原理自然观察。

英文摘要:

After revealing difficulties of the standard time-dependent perturbation theory in quantum mechanics mainly from the viewpoint of practical calculation, we propose a new quasi-canonical perturbation theory. In the new theory, the dynamics of physical observables, instead of that of coefficients of wave-function expansion, is formulated so that the gauge-invariance and correspondence principles are observed naturally.
