✦ Synopsis

The study of the soliton states in the system formed by three parallel chains shows that there appear three soliton types. We made a comparison of two theoretical approaches used in this case. Davydov's method, previously applied in the study of alpha-helix, leads to only one type of antisymetric solitons in this case. A perturbational treatment whose zero-order approximation describes real vibron states, leads to three different soliton types for three parallel chains.

We present analytic results of soliton shapes propagating in an absorbing three-level atomic system in the lambda configuration which is excited by a CW field at the Stokes transition. We find analytic relations for the control of the propagation velocity which can be influenced by the pulse width a

## Abstract In the case of constant electron density along the chain the two‐soliton solution is given explicitly. For simplification the coupling between electronic system and lattice is neglected.
