Abstract
The exact semiclassical wavefunction for a tunneling electron, coupled to the degrees of freedom of the host medium, is constructed. As a specific application, the result is used to calculate the tunneling amplitude for the electron interacting with a single vibrational mode of the medium. In agreement with previous numerical studies, the tunneling rate is enhanced due to the interaction-stimulated decrease of the tunneling barrier. Several tunneling regimes can be distinguished, depending on the relationship of vibrational frequency and tunneling time.
