电子附着的运动方程腔量子电动力学耦合团簇理论
Equation-of-motion cavity quantum electrodynamics coupled-cluster theory for electron attachment
摘要：
在腔量子电动力学（QED）框架下，将电子附着变体的运动方程耦合团簇理论（EOM-EA-CC）推广到强光-物质耦合的情形。由此产生的EOM-EA-QED-CC形式主义提供了一个从头算，相关的，和非微扰描述的腔诱导效应在多电子系统，补充其他最近提出的腔QED耦合集群理论的扩展。重要的是，这项工作表明，EOM-CC理论的QED推广是有用的框架，探索粒子非保守部门的福克空间，从而建立了一条道路前进的同时描述强电子-电子和电子-光子相关效应。
英文摘要：
The electron attachment variant of equation-of-motion coupled-cluster theory (EOM-EA-CC) is generalized to the case of strong light-matter coupling within the framework of cavity quantum electrodynamics (QED). The resulting EOM-EA-QED-CC formalism provides an ab initio, correlated, and non-perturbative description of cavity-induced effects in many-electron systems that complements other recently proposed cavity-QED-based extensions of coupled-cluster theory. Importantly, this work demonstrates that QED generalizations of EOM-CC theory are useful frameworks for exploring particle non-conserving sectors of Fock space, thereby establishing a path forward for the simultaneous description of both strong electron-electron and electron-photon correlation effects.
