Mobile Bipolarons in the Adiabatic Holstein-Hubbard Model in 1 and 2 dimensions
Laurent Proville, Serge Aubry
The bound states of two electrons in the adiabatic Holstein-Hubbard model are studied numerically in one and two dimensions from the anticontinuous limit. This model involves a com…
Small Bipolarons in the 2-dimensional Holstein-Hubbard Model. II Quantum Bipolarons
Laurent Proville, Serge Aubry
We study the effective mass of the bipolarons and essentially the possibility to get both light and strongly bound bipolarons in the Holstein-Hubbard model and some variations in t…
Small Bipolarons in the 2-dimensional Holstein-Hubbard Model. I The Adiabatic Limit
Laurent Proville, Serge Aubry
The spatially localized bound states of two electrons in the adiabatic two-dimensional Holstein-Hubbard model on a square lattice are investigated both numerically and analytically…
Growth and decay of discrete nonlinear Schroedinger breathers interacting with internal modes or standing-wave phonons
Magnus Johansson, Serge Aubry
We investigate the long-time evolution of weakly perturbed single-site breathers (localized stationary states) in the discrete nonlinear Schroedinger (DNLS) equation. The perturbat…
