论文摘要
为了将发电机坐标方法应用于大型配置空间，我们提出了一个简单的近似公式来计算绝热多体矩阵元素，而无需评估两体相互作用矩阵元素。该方法用基于谐波振荡器的两个分析可解决的哈密顿量进行了说明。
With a view to applying the Generator Coordinate Method to large configuration spaces, we propose a simple approximate formula to compute diabatic many-body matrix elements without having to evaluate two-body interaction matrix elements. The method is illustrated with two analytically solvable Hamiltonians based on the harmonic oscillator.
