Rayleigh-Schrödinger Perturbation Theory Based on Gaussian Wavefunctional Approch
Wen-Fa Lu, Chul Koo Kim, Jae Hyung Yee +1
A Rayleigh-Schrödinger perturbation theory based on the Gaussian wavefunctional is constructed. The method can be used for calculating the energies of both the vacuum and the excit…
