AI 中文摘要
兰姆移位是原子物理学中最基础的相互作用之一，源于氢原子（H原子）与量子真空的电磁涨落之间的相互作用，该能量移位已通过多种方式计算得出。费曼（Feynman）与鲍尔（Power）证明，该能量移位等于包含氢原子的体积内真空能量的变化，这种变化由氢原子存在引起的折射率改变产生。利用这一结果，结合群论计算真空涨落各频率对兰姆移位的贡献，可得到氢原子周围因兰姆移位产生的、对应各频率ω的真空能量区域大小的表达式：基态原子被正真空能量区域包围，低频时该区域远超出原子本身，可描述为稳态虚量子云；当能量E=ħω小于1 eV时，正能区域半径约为14.4/E埃，对应波长为λ的真空涨落，半径为(α/2π)λ，因此长波长下该区域具有宏观尺寸；能量-时间不确定关系预测的最大可能半径比该值大1/(4α)倍。
英文摘要
\abstract{The Lamb shift, one of the most fundamental interactions in atomic physics, arises from the interaction of H atoms with the electromagnetic fluctuations of the quantum vacuum. The energy shift has been computed in a variety of ways. The energy shift, as Feynman and Power demonstrated, equals the change in the vacuum energy in the volume containing the H atoms due to the change in the index of refraction arising from the presence of the H atoms. By using this result and a group theoretical calculation of the contribution to the Lamb shift from each frequency of the vacuum fluctuations, we can obtain an expression for the size of the region of vacuum energy for each frequency \texorpdfstring{$ω$}{ω} around the H atom due to the Lamb shift. The ground state atom is surrounded by a region of positive vacuum energy that extends well beyond the atom for low frequencies. This region can be described as a steady state cloud of virtual quanta. For energies \texorpdfstring{$E=\hbarω$}{E=hbar omega} eV less than 1 eV, the radius of the positive energy region is approximately 14. 4/E Angstroms. For a vacuum fluctuation of wavelength \texorpdfstring{$λ$}{lambda} the radius is \texorpdfstring{$(α/2π)λ$}{(alpha/2pi) lambda}. Thus, for long wavelengths, the region has macroscopic dimensions. The energy-time Uncertainty Relation predicts a maximum possible radius that is larger than this by a factor of \texorpdfstring{$1/ 4α$}{1/(4 alpha)}.} \keyword{Bethe; radiative shift; shift spectral density; spectral volume; vacuum fluctuations; vacuum field; Lamb shift; QED; energy field, renormalization, zero point fluctuations; hydrogen atom}.
