## Abstract The selfβenergy of the oneβmode polaron model is calculated in both the weak and strong coupling regimes by using a variational principle which removes all linear Bose coupling terms and diagonalizes all quadratic Bose terms in the Hamiltonian. It is clearly demonstrated that this appro
