量子算符形式论的物理起源

On the physical origin of the quantum operator formalism

Ana María Cetto, Luis de la Peña, Andrea Valdés-Hernández

摘要:

通过重新审视真空场在量子力学中的作用,我们为量子算符形式主义的出现提供了一个清晰的物理解释。真空或随机零点辐射场以前已经被证明,使用随机电动力学的工具,在允许粒子受到保守约束力以达到静止运动状态方面是中心的。在这里,我们专注于定态,并考虑真空作为驱动力的作用。我们观察到,粒子共振响应某些场模式。对这种响应的适当的哈密顿分析使我们能够通过在x和p的响应系数与各自的矩阵元素之间建立一一对应来明确地追踪基本量子交换子的起源。(随机)驱动场变量因此从描述中消失,但它们的哈密顿性质在算子形式中得到体现。海森堡方程建立了响应函数之间的动力学关系。

英文摘要:

We offer a clear physical explanation for the emergence of the quantum operator formalism, by revisiting the role of the vacuum field in quantum mechanics. The vacuum or random zero-point radiation field has been shown previously, using the tools of stochastic electrodynamics, to be central in allowing a particle subject to a conservative binding force to reach a stationary state of motion. Here we focus on the stationary states, and consider the role of the vacuum as a driving force. We observe that the particle responds resonantly to certain field modes. A proper Hamiltonian analysis of this response allows us to unequivocally trace the origin of the basic quantum commutator, by establishing a one-to-one correspondence between the response coefficients of x and p and the respective matrix elements. The (random) driving field variables disappear thus from the description, but their Hamiltonian properties become embodied in the operator formalism. The Heisenberg equations establish the dynamical relationship between the response functions.
