Abstract: The translationally invariant polaron theory of Tulub, which does not involve Pekar's ansatz (believed to provide an asymptotically exact solution in the strong-coupling limit) and fundamentally produces a lower-energy polaron than when using the ansatz, is discussed in detail. For the bipolaron, the theory yields the best values for bonding energy and for critical stability parameters. A variety of physical implications of the existence of translationally invariant polarons and bipolarons are discussed.
