论文摘要

自1948年以来就一直在实验证明自1948年以来,Casimir效应 - 两个非电荷导电板彼此具有弱但可测量的力,这取决于它们之间的距离的反相反的第四功率,它们表明了真空吸尘器零点波动的现实。在1948年后的许多量子场理论书籍和论文中都重复了真空波动现实的“证明”。吸引力通常归因于板和真空之间电磁场的零点能量的差异。众所周知,零点真空波动与相对论物理学不相容,并且是“宇宙常数”问题的根源。关于量子力学和量子场理论的大多数文本都通过正常排序或其他机制消除了真空能量。本文探讨了这些问题,并指出解决方案的一种方法已经存在。

It has been argued since 1948, when it was experimentally demonstrated, that the Casimir effect-where two non-charged conducting plates have a weak but measurable force on each other dependent on the inverse fourth power of the distance between them-shows the reality of vacuum zero-point fluctuations. This "proof" of the reality of vacuum fluctuations has been repeated in many quantum field theory books and papers subsequent to 1948. The attractive force is generally ascribed to the difference in zero-point energy of the electromagnetic field between the plates and the vacuum external to them. As is well known, zero-point vacuum fluctuations are incompatible with relativistic physics and are at the root of the "cosmological constant" problem. Most texts on quantum mechanics and quantum field theory eliminate the vacuum energy by normal ordering or some other mechanism. These issues are explored in this paper and it is pointed out that a means to resolve them already exists.
