Abstract
Self-trapped carriers of large bipolarons are redistributed among site s of their molecular orbitals in response to atomic motions. This effe ct lowers the phonon frequencies. The dependence of the zero-point ene rgy on the spatial distribution of large bipolarons produces a phonon- mediated attraction between them. This dynamic quantum-mechanical effe ct fosters the condensation of large bipolarons into a liquid at suffi ciently low temperatures.
