Abstract

The Fulton-Gouterman transcription (=parity ordering) of the archetype Hamiltonian of phonon-assisted tunneling reveals a reflective property, by means of which the Debye-Waller peculiarity is established as a topological phenomenon. By means of a reflective unitary transformation it is shown that this phenomenon establishes a logarithmic suppression of localization for an “Ohmic dissipation” coupling law. Further consequences (“mode mixing”) for quantum diffusion are also indicated.
