Abstract
If the polaron coupling constant α is large enough bipolarons or multipolarons will form When passing through the critical α c from above does the radius of the system simply get arbitrarily large or does it reach a maximum and then explode We prove that it is always the latter We also prove the analogous statement for the PekarTomasevich PT approximation to the energy in which case there is a solution to the PT equation at α c Similarly we show that the same phenomenon occurs for atoms eg helium at the critical value of the nuclear charge Our proofs rely only on energy estimates not on a detailed analysis of the Schrödinger equation and are very general They use the fact that the Coulomb repulsion decays like 1/r while ‘uncertainty principle’ localization energies decay more rapidly as 1/r 2
