    "abstract": "This paper promotes the differential method as a new fruitful strategy for\nestimating a ground-state energy of a many-body system. The case of an\narbitrary number of attractive Coulombian particles is specifically studied and\nwe make some favorable comparison of the differential method to the existing\napproaches that rely on variational principles. A bird\u0027s-eye view of the\ntreatment of more general interactions is also given.",
