Abstract
The ground state of a quasiparticle (exciton, electron or hole) intera cting with dispersionless optical vibrations in a one-dimensional chai n is investigated using the variational approach. The phase diagram fo r the quasiparticle states depending on the values of the parameters o f the system, such as the nonadiabaticity parameter and the electron-p honon coupling constant, is obtained. A comparison of the results with experimental data is given.
