中文摘要

计划开发和应用两种新的下一代高精度多体形式化。一种是广义变分耦合簇法，另一种是直接计算四阶多体微扰理论。它们将在碱金属原子的高精度实验数据上进行测试。这些方法将改善宇称非守恒测量的高精度解释的基础，限制对基本粒子标准模型的扩展。它们将允许高精度地描述远程相互作用，这对超冷碰撞研究至关重要。
英文摘要
It is planned to develop and apply two new next-generation high precision many-body formalisms. One is a generalized cariational coupled-cluster method, the other the direct evaluation of fourth-order many-body perturbation theory. They will be tested on high precision experimental data for alkali-metal atoms. The approaches will improve the basis for high-precision interpretations of parity-nonconservation measurements, constraining extensions to the standard model of elementary particles. They will permit the high precision description of long-range interactions, crucial to ultra-cold collision studies.
