Soliton Propagation in One-Dimensional Organic Conductors.
Abstract
Criteria are stated for the existence of solitons in one-dimensional organic conductors, particularly trans polyacetylene. All physical situations considered are described in terms of a classical anharmonic oscillator moving in an anharmonic double potential well. As the solition is known to exist in the line of pendula joined with elastic coupling and also in the long Josephson junction in the form of the fluxon, the theoretical position is taken that if, indeed, the soliton exists in polymers, whether of the vibrational or the charge-domain-wall-type, then it should conform to certain established criteria of behavior already rigorously studied in the aforementioned situations. In order to understand the dynamics of a conducting one-dimensional system, whether or charge or mechanical energy, a microscopic parametric excitation model formalism must be adopted. On the other hand, in order for this model to be related to physical measurements such as that of current and voltage, a microscopic formalism (the Hubbard model) must also be achieved. Both pictures have advantages and disadvantages. However, both pictures are necessary for complete understanding.
