We investigate atomistic-to-continuum coupling mechanisms for this atomistic model, paying special attention to the dependence of the atomistic subproblem on the atomistic region boundary and the boundary conditions. We rigorously prove first-order error estimates for two related coupling mechanisms.", "revisions": [ { "version": "v1", "updated": "2011-12-04T11:27:33.000Z" } ], "analyses": { "subjects": [ "65N12", "65N15", "70C20" ], "keywords": [ "density functional theory", "one-dimensional toy model", "atomistic-to-continuum coupling approximation", "atomistic model", "coupling mechanisms" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1112.0746L" } } }
