From weak to strong: Constrained extrapolation of perturbation series with applications to dilute Fermi systems
We develop a method that uses truncation-order-dependent reexpansions constrained by generic strong-coupling information to extrapolate perturbation series to the nonperturbative regime. The method is first benchmarked against a zero-dimensional model field theory and then applied to the dilute Ferm...
