Coherent soliton states are analysed using the equivalent Boson Hamiltonian for excitons. This equivalent Hamiltonian includes the exciton concentrations corresponding to the Tyablikov approximation in the theory of magnetism. Soliton spectra were de

In this paper we analyze the electron states in metallic films. The first part of the paper is devoted to the study of the film where ion-ion interaction changes only in boundary layers. It was concluded that bulk states always appear in such film. S

In order to define a statistical method of the analysis of mass heterogeneous structures, we have formulated stochastic and dynamic mass distribution in these structures. The expressions derived were used to calculate some of the basic characteristic

A procedure is proposed enabling the substitution of a translationally non-invariant one-dimensional structure with unequal neighbouring spacing by a statistically equivalent ideal structure with equal spacing between neighbouring molecules. A proced

Using Frohlich transformations, a system of interacting excitons and phonons, is substituted by an equivalent system of interacting excitons. It was concluded, by this approach that solitons can be formed only by coherent excitons. It was also shown,

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 alph

Our aim is to study the influence of Davydov splitting onto the properties of solitons in ∝-proteins. We are going to demonstrate how different approaches lead to nearly same soliton properties.

It is shown, using the equations of motion for exciton and phonon operators, that solitons can arise in the space of coherent excitonic states only. The results obtained by this strictly quantum approach are compared to the corresponding ones of Davy

The behaviour of quasi-one-dimensional ferroelectrics of the KDP-family is investigated in the vicinity of the transition temperature. Three forms of the proton–proton potential are examined and it is concluded that long-range forces are responsibl
