AI 中文摘要
在量子电动力学框架内，分析了两个远距离原子之间的相互作用。利用S矩阵形式体系，推导出磁相互作用势的表达式，该表达式与经典电动力学的著名结果一致。然而，量子电动力学超越了这一传统结果，能够处理与原子能级结构相关的广泛问题。特别是，结果表明相互作用势的渐近行为可能偏离经典预测，这取决于所涉及的原子状态。例如，计算了氢原子s态的色散系数，其中长程势简化为自旋-自旋相互作用。所得结果为直接比较物质和反物质原子之间的长程相互作用势提供了可能。该方法在氢-反氢系统中的适用性得到了证明。
英文摘要
Within the framework of quantum electrodynamics, the interaction between two atoms at large distances is analyzed. Using the S-matrix formalism, an expression for the magnetic interaction potential is derived, which agrees with the well-known result of classical electrodynamics. However, quantum electrodynamics goes beyond this conventional result and allows one to treat a wide range of problems related to the structure of atomic energy levels. In particular, it is shown that the asymptotic behavior of the interaction potential can deviate from the classical prediction, depending on the atomic states involved. As an example, dispersion coefficients are calculated for the s-states of hydrogen atoms, where the long-range potential reduces to a spin-spin interaction. The results obtained open up the possibility of a straightforward comparative analysis of long-range interaction potentials between atoms of matter and antimatter. The applicability of this approach is demonstrated for the hydrogen-antihydrogen system.
