This Review is devoted to the presentation of the exact factorization as a framework employed to study a variety of quantum-mechanical many-body problems. Since its original formulation in the 70s, the main applications of the exact factorization were directed towards understanding the properties of multi-component systems, e.g. electron-nuclear systems. Especially in the electron-nuclear case, the exact factorization is viewed as an exactification of the Born-Oppenheimer approximation, thus it was, and still is, largely employed in nonadiabatic dynamics. Nonetheless, as early as the 80s, the formalism was employed to study many-electron interacting systems and, quite recently, i.e. less than a decade ago, it was extended to study the behavior of molecules in the context in cavity quantum electrodynamics. These formulations, perhaps less popular than the electron-nuclear formulation, have attracted a lot of attention over the years. Therefore, we review here the exact electron-only factorization and the exact photon-electron-nuclear factorization.

本文用Born-Oppenheimer(BO)乘积波函数分析法和相空间束缚轨线法解析地求解了两个双线性耦合谐振子系统[J. S. Molano等人,化学物理快报\textbf{76}(12),138171(2021)]。双线性耦合振荡器系统允许获得量子系统的解析表达式,便于与使用BO拟积的结果进行比较。解析和BO波函数作为抛物柱面函数的乘积得到。精确和BO波函数的抛物柱面函数的自变量通过线性变换与物理坐标相关,分别由矩阵$\mathsf{G}$和$\mathsf{\tilde{G}}$表示。矩阵$\mathsf{G}$的$QU$分解输出与BO $\mathsf{\tilde{G}}$矩阵密切相关的上三角矩阵$\mathsf{U}$。分析了BO非绝热耦合对相空间运动方程稳定性的影响。由Born-Oppenheimer相空间轨迹法得到的本征值和本征函数与解析解非常吻合。
