On Davydov Solitons at 310 K

  • A. C. Scott


Recent numerical studies of Davydov solitons at physiological temperature are in disagreement with a previous theoretical analysis by Davydov. It is suggested that the disagreement arises because the specific assumption concerning the introduction of temperature in the numerical experiments leads to a mechanism for soliton decay (a soliton-exciton transition) that is forbidden by the Franck-Condon principle. The temperature dependence of the Davydov soliton must be governed by other mechanisms.
