We have included nonadiabatic effects in the calculation of the dynamical evolution of a system where a quantum particle in a double well is coupled to a classical oscillator. By performing an exponential resummation of the evolution operator we have included "polarization" effects (similar to the self-energy corrections for an electron that moves in a polarizable medium) which lead to a renormalizatiori of the energy of the quantum particle.
