Universality in SRG Evolved Potentials and the Choice of an Efficient Potential

Two-body nuclear observables can be accurately described using a variety of potentials. Using the similarity renormalization group (SRG), evolved interactions exhibit universality in the low energy regime. One can exploit this universality by choosing a computationally efficient potential. A separable potential from inverse scattering is one such analytically simple potential. With a simple solution to the two-body interaction, one can more efficiently solve few- and many-body problems.
