摘要:

量子力学的基本问题之一,是找到经典可观测量的正确量子图像,使其能够对应于实验测量。我们研究恰当的量子化规则,该规则应产生一个服从哈密顿运动方程的量子类比形式的哈密顿量,其中包括算子相对于另一个算子的微分。为赋予此类微分以意义,Born和Jordan建立了两种定义,分别称为第一类微分商和第二类微分商。本文修改了第一类微分商的定义,并针对对应于不同量子化的不同基算子,证明了它与第二类微分商的一致性。文中还研究了相关定理和微分规则,包括负幂算子的微分以及多重微分。我们表明,由Weyl量子化、最简单对称量子化和Born-Jordan量子化得到的哈密顿量,均满足量子运动方程所要求的代数。

英文摘要:

One of the fundamental problems in quantum mechanics is finding the correct quantum image of a classical observable that would correspond to experimental measurements. We investigate for the appropriate quantization rule that would yield a Hamiltonian that obeys the quantum analogue of Hamilton's equations of motion, which includes differentiation of operators with respect to another operator. To give meaning to this type of differentiation, Born and Jordan established two definitions called the differential quotients of first type and second type. In this paper we modify the definition for the differential quotient of first type and establish its consistency with the differential quotient of second type for different basis operators corresponding to different quantizations. Theorems and differentiation rules including differentiation of operators with negative powers and multiple differentiation were also investigated. We show that the Hamiltonian obtained from Weyl, simplest symmetric, and Born-Jordan quantization all satisfy the required algebra of the quantum equations of motion.
