Quantum-mechanical derivation of the equations of motion for Davydov solitons
Abstract
The equations of the Davydov model, which describe energy propagation along linear-chain molecules by a soliton mechanism, have heretofore been derived by a combination of quantum-mechanical and classical techniques. We give here a derivation which is completely based on quantum mechanics.
