Abstract. The work is devoted to obtaining the bipolaron functional in anisotropic crystals by Buimistrov-Pekar method for an arbitrary electron-phonon coupling. The effect of electron correlations related to the direct dependence of the wave function from the distance between the electrons on bipolaron energy is studied. The single-center and two-center (coaxial configuration) bipolaron models in crystals with anisotropic effective mass for the limiting case of quasi-systems (the system “light axis”) were compared.
Key words: electron-phonon interaction, anisotropic crystals, polaron, bipolaron.
