A model of a dielectric or an elastic superlattice is proposed which describes quite simply the frequency spectrum of electromagnetic or acoustic waves. The frequency band spectrum of a one-dimensional lattice consists of minibands, which narrow down

The spectrum of oscillations localized near an interface between two identical infinite layered crystals is studied. It is shown that some important characteristics of oscillations polarized normally to the layers in layered crystals are almost compl

The possibility of Bose-Einstein condensation of a nonideal 2D Bose gas in an anti-trap external field is studied. The problem is solved exactly for the external potential of a special form u(x) = μ - u cosh 2 (x/l), where μ -is the chemical potent

Vibrations localized near the surface have been analyzed by the Jacobian matrix method taking into account discreteness of the lattice. It has been shown that localized surface vibrations in layered crystals with the complex lattice have quasi-one-di

Exact analytic expressions for local densities of atoms of the system as functions of the distance to a defect as well as defect parameters (variations of mass and force constants) are derived for an semi-infinite linear chain with an impurity at the

Exact analytic expressions for Green’s functions of the chain type structures with defects in an external periodic field are obtained by the method of Jacobi matrices. A diatomic impurity molecule in a monatomic chain as well as adsorbed chains wit

Exact analytic expressions are obtained for Green’s functions of a linear chain with a diatomic unit cell containing an isotopic substitutional impurity. An infinite chain as well as a semi-infinite chain with an impurity at the free end are consid
