Abstract:
The ground-state energies of large polaron E p and bipolaron E B in three-dimensional lightly doped cuprates are calculated variationally taking into account the short- and long-range electron-phonon interactions and Coulomb correlation in the continuum model and adiabatic approximation. The binding energy of a large bipolaron and its stability region are determined as a function of the ratio of dielectric constants η = ε ∞ /ε 0 . It is found that the large bipolaron is stable in a broad region of η.
