Namely, the spatio-time evolution 43 of the self-induced localized mode is described by the Bessel functions, and the dispersion relation for the eigenfrequency of the localized mode constitutes a frequency band, where its binding energy generally depends on the wave number of the localized mode as well.

The Hubbard model. In your approach, the electron-electron correlations enter only indirectly via the electron-phonon coupling. Could you elaborate on the justification for neglecting the direct electron-electron interaction in your Hamiltonian? Reply: I think a model that assumes only electron-electron interactions does not explain the pairing of electrons. In the Hubbard model, the energy of a pair on one site is higher than the energy of free particles. So one finds not stationary but virtual states, which decay.

Superconductivity seen above the boiling point of nitrogen. Physics Today 40, no. 4,17 (1987). 21 Question by Kenkre: Solitons are, as is generally known, one-dimensional objects. HighTc superconductors, on the other hand, have 2-dimensional and 3-dimensional structure. Why does this not present problems for your theory? Is it perhaps that by bisolitons you merely mean bipolarons?
