In the Hartree-Fock-Bogoliubov approximation, we solve the gap equation for spin-polarized electrons at the half-filled Landau levels. We obtain an effective Hamiltonian which shows a continuous transition from the compressible striped state to the paired state. Furthermore, a crossover occurs in the pairing phase. The energy spectrum and energy gap of the quasiparticle in the paired state is calculated numerically at the half-filled second Landau level.", "revisions": [ { "version": "v2", "updated": "2000-11-30T05:12:16.000Z" } ], "analyses": { "subjects": [ "73.40.Hm", "74.20.Fg", "71.45.Lr" ], "keywords": [ "half-filled landau level", "paired state", "effective hamiltonian", "magnetic translations commute", "half-filled second landau level" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier", "journal": "Nucl.
