Two-Dimensional Anharmonic Crystal Lattices: Solitons, Solectrons, and Electric Conduction
Manuel G. Velarde, Werner Ebeling, Alexander P. Chetverikov
Reported here are salient features of soliton-mediated electron transport in anharmonic crystal lattices.After recalling how an electron-soliton bound state (solectron) can be form…

Quartic Lattice Interactions, Soliton-like Excitations and Electron Pairing in One-Dimensional Anharmonic Crystals
M. G. Velarde, L. Brizhik, A. P. Chetverikov +3
We show that two added, excess electrons with opposite spins in one-dimensional crystal lattices with quartic anharmonicity may form a bisolectron, which is a localized bound state…

On Electron Pairing in One-Dimensional Anharmonic Crystal Lattices
M. G. Velarde, L. Brizhik, A. P. Chetverikov +3
We 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 t…
