The breakdown of conductance quantization in a quantum point contact in the presence of random long-range impurity potential is discussed. It is shown that in the linear response regime a decisive role is played by the indirect backscattering mechani

Early experiments on quasicrystals and their approximants revealed their unusual optical properties: no Drude peaks were observed; instead, a.c. conductivity linearly increased with frequency. Several theories have been proposed to explain this linea

We present a new formalism for the explanation of the curvature of the Arrhenius self-diffusion plots on the basis of mono-vacancy diffusion mechanism. The temperature dependence of the diffusion coefficient appears from the concentration dependence

We present the result of ab initio calculations of the electronic structure for series of Fe100-xBx and Ni100-xBx crystalline and amorphous alloys. DOSs of iron and nickel borides of the same composition have almost the same shapes, rigidly shifted w

We have performed an extensive study of the electronic structure, optical properties, and electron-energy-loss spectra (EELS) for the series of the ${\mathit{M}}_{3}$B, ${\mathit{M}}_{2}$B, and MB (M=Fe, Ni) crystalline alloys. The electron density o

The change in slope of the Arrhenius curve for the diffusion coefficient as a function of temperature is discussed, and its occurence is explained by vacancies concentration dependence of the formation energy. It is shown that a sign of the mixing en

The electronic Raman continuum in YBa 2 Cu 3 O 7 is calculated in a model which takes into account strong inelastic scattering and interband transitions. The ab-plane polarised continuum contains a large contribution from interband processes and does
