我们提出了一种有效的方法，电子关联问题，非常适合于强相互作用的多体系统，但只需要平均场的计算成本。我们的方法的性能示出了一维哈伯德环与不同数量的网站，和非相对论性量子化学哈密顿探索对称解离的H-50氢链。
We present an efficient approach to the electron correlation problem that is well suited for strongly interacting many-body systems, but requires only mean-field-like computational cost. The performance of our approach is illustrated for one-dimensional Hubbard rings with different numbers of sites, and for the nonrelativistic quantum-chemical Hamiltonian exploring the symmetric dissociation of the H-50 hydrogen chain.
