Using an adiabatic approximation based on action-angle variables, we present solutions for the effective charge of the Coulomb interaction (screening) for a vertical confinement potential simulated by parabolic, square, and triangular wells. While for the parabolic potential the solution for the effective charge is given in a closed anlytical form, for the other cases similar solutions can be easily calculated numerically.", "revisions": [ { "version": "v1", "updated": "2008-09-24T21:12:01.000Z" } ], "analyses": { "subjects": [ "03.65.Sq", "31.15.xg", "73.21.La" ], "keywords": [ "coulomb interaction", "magnetic field", "confined electrons", "dynamical screening", "axially symmetric three-dimensional potential" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "year": 2008, "month": "Sep", "volume": 78, "number": 3, "pages": "032115" }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvA..78c2115S" } } }
