论文摘要
电子结构计算的最终目标是使标题为``方程式''的左侧和右侧尽可能接近。这需要对相对论，相关性和量子电动力学（QED）效应进行高精度处理。尽管相对论和QED效应都可以很容易地内置在许多电子哈密顿量中，但由于波函数中参数数量的指数增长，电子相关性更难描述。与无自旋情况相比，自旋轨道相互作用导致自旋对称性和随之而来的复合代数的丧失，从而使电子相关性的处理更加困难。这里突出显示了这些问题的可能解决方案。
The ultimate goal of electronic structure calculations is to make the left and right hand sides of the titled ``equation'' as close as possible. This requires high-precision treatment of relativistic, correlation, and quantum electrodynamics (QED) effects simultaneously. While both relativistic and QED effects can readily be built into the many-electron Hamiltonian, electron correlation is more difficult to describe due to the exponential growth of the number of parameters in the wave function. Compared with the spin-free case, spin-orbit interaction results in the loss of spin symmetry and concomitant complex algebra, thereby rendering the treatment of electron correlation even more difficult. Possible solutions to these issues are highlighted here.
