Quantum Effects on the Davydov Soliton

  • H. Bolterauer
Part of the NATO ASI Series book series (NSSB, volume 243)


A simple method is introduced to calculate the quantum lifetime of a Davydov soliton. We calculate the quantum lifetime for the usual parameter set in the Hamiltonian. The influence of the quantum number and of a prior excited lattice on this lifetime is shown. An important result is that the Davydov ansatz is exact for a classical lattice. For this case, the soliton is stable against quantum fluctuations.
