  author={Amir H. Rezaeian and Niels R. Walet},
Abstract The coupled cluster method (CCM) is one of the most successfu l and universally applicable techniques in quantum many-body theor y. The intrinsic nonlinear and non-perturbative nature of the method is cons idered to be one of its advantages. We present here a combination of CCM with t he Wilsonian renormalization group which leads to a powerful… CONTINUE READING
