论文摘要
原子和分子系统中的相互作用由电磁力支配，理论框架必须在量子状态下。量子力学和电磁学结合的物理理论，量子电动力学已经建立了二十世纪中叶，主要是作为散射理论。要描述原子和分子，重要的是要考虑结合状态。在非相关主义量子力学框架中，可以使用稳健和一般方法有效地计算有界面状态，该方法具有用于求解波方程的系统近似值。随着针对原子和分子物质的计算量子电动力学框架的开发，在时空坐标中表达的现场理论伯特贝尔 - 盐波方程，综述了其确切的相对时间变体和相对论波方程的出现。还强调了一个具有初始应用和未来挑战的计算框架与精确光谱相关。
Interactions in atomic and molecular systems are dominated by electromagnetic forces and the theoretical framework must be in the quantum regime. The physical theory for the combination of quantum mechanics and electromagnetism, quantum electrodynamics has been established by the mid-twentieth century, primarily as a scattering theory. To describe atoms and molecules, it is important to consider bound states. In the non-relativistic quantum mechanics framework, bound states can be efficiently computed using robust and general methodologies with systematic approximations developed for solving wave equations. With the sight of the development of a computational quantum electrodynamics framework for atomic and molecular matter, the field theoretic Bethe-Salpeter wave equation expressed in space-time coordinates, its exact equal-time variant and emergence of a relativistic wave equation is reviewed. A computational framework, with initial applications and future challenges in relation with precision spectroscopy, is also highlighted.
