We derive an upper bound on the ground state energy of the system at the leading order using a Jastrow factor. Our result matches the lower bound proven by Nam-Ricaud-Triay and therefore resolves the leading order. Moreover, a straightforward adaptation of our proof can be used for systems interacting via combined two-body and three-body interactions to generalise Theorem 1.2. from arXiv:2402.05646 to hard-core potentials.", "revisions": [ { "version": "v1", "updated": "2024-06-13T11:44:22.000Z" } ], "analyses": { "keywords": [ "ground state energy", "dilute bose gas", "three-body hard-core interactions", "three-body hard-core potential", "lower bound proven" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
