Analysis shows single reference methods based on richardson–gaudin states yield efficient results in strong correlation scenarios, suggesting a feasible approach.
Strongly correlated systems are well described as a configuration interaction of Slater determinants classified by their number of unpaired electrons. This treatment is, however, unfeasible. In this paper, it is demonstrated that single reference methods built from Richardson–Gaudin states yield comparable results at polynomial cost.
