We have shown that for a typical range of DNA parameters, formation of the bound state of two holes at the same guanine trap is possible for the GGG and GGGG traps if the hole-hole interaction is weak, which can be achieved for the DNA in solutions. The origin of the two-hole bound state is the competition between the Coulomb repulsion and the phonon mediated attraction between the holes. For the hole-phonon coupling constant $\\approx 1$ two holes will be at the same trap if the on-site hole-hole repulsion energy is $\\lesssim 0.9 $ eV.", "revisions": [ { "version": "v1", "updated": "2005-07-07T16:32:55.000Z" } ], "analyses": { "keywords": [ "energetics", "guanine trap", "on-site hole-hole repulsion energy", "two-hole bound state" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005cond.mat..7179A" } } }
