摘要

在量子电动力学（QED）中，我们计算了氢原子基态O（α）阶动量-电流密度Tij的引力张量-单极矩。得到τH/τ0−1=4α3π(lnα2−0.028)= - 3.06×10−2，其中τ0= 2/4me为一级矩。次一级修正的物理原理类似于著名的能级兰姆位移。2024年由美国物理学会出版

Gravitational tensor-monopole moment of the hydrogen atom to order O(α)
We calculate the gravitational tensor-monopole moment of the momentum-current density Tij in the ground state of the hydrogen atom to order O(α) in quantum electrodynamics (QED). The result is τH/τ0−1=4α3π(lnα2−0.028)=−3.06×10−2 where τ0=ℏ2/4me is the leading-order moment. The physics of the next-to-leading-order correction is similar to that of the famous Lamb shift for energy levels. Published by the American Physical Society 2024
