A Polaron is a particle in a cloud of phonons. Bipolarons are bound states of two particles in a phonon cloud. Here, we present results for Peierls bipolarons. We find that phonon-mediated effects are non-trivial. In presence of strong bare interactions, the ground state has a rich phase diagram exhibiting non-analytic transitions, one of which is a quasi self-trapping transition.
