Electron pairing in one-dimensional anharmonic crystal lattices, International Journal of Quantum Chemistry, 112, 2, 551-565, 2012.0020-7608AUT: LHA01632http://hdl.handle.net/10400.1/3571We show that when anharmonicity is added to the electron–phonon interaction it facilitates electron pairing in a localized state. Such localized state appears as singlet state of two electrons bound with the traveling local lattice soliton distortion, which survives when Coulomb repulsion is included.engElectron pairingLattice solitonAnharmonic latticeSolectronBisolectronjournal article2014-02-27http://dx.doi.org/10.1002/qua.23008
