Pekar's ansatz and the strong coupling problem in polaron theory
V. D. Lakhno Institute of Mathematical Problems of Biology, Russian Academy of Sciences, Pushchino, Moscow region
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.
