Elastic model of dry friction
Autor: A. I. Larkin, D. E. Khmelnitskii
Publikováno v: Journal of Experimental and Theoretical Physics. 117:399-406
Friction of elastic bodies is connected with the passing through the metastable states that arise at the contact of surfaces rubbing against each other. Three models are considered that give rise to the metastable states. Friction forces and their de

On low-temperature properties of uniaxial dielectrics with a soft optic mode
Autor: D. E. Khmelnitskii
Publikováno v: Journal of Experimental and Theoretical Physics. 118:133-135
Dielectric properties, thermal expansion, and the rate of spin-lattice relaxation at low temperatures in uniaxial dielectrics with a soft optical mode are discussed.

Level statistics in a two-dimensional disk with diffusive boundary scattering
Autor: D. E. Khmelnitskii, V. Tripathi
Publikováno v: Physical Review B. 58:1122-1125
We calculate the energy level statistics in a two-dimensional disk with diffusive boundary scattering by the means of the recently proposed ballistic nonlinear \ensuremath{\sigma} model [B. A. Muzykantskii and D. E. Khmelnitskii, JETP Lett. 62, 76 (1

A renormalization group approach to the Coulomb gap
Autor: D. E. Khmelnitskii, S. R. Johnson
Publikováno v: Journal of Physics: Condensed Matter. 8:3363-3372
The free energy of the Coulomb gap problem is expanded as a set of Feynman diagrams, using the standard diagrammatic methods of perturbation theory. The gap in the one-particle density of states due to long-ranged interactions corresponds to a renorm

On quantum shot noise
Autor: B. A. Muzykantskii, D. E. Khmelnitskii
Publikováno v: Physica B: Condensed Matter. 203:233-239
We discuss the distribution function for the current noise in quantum point contacts. Special interest is paid to a contact of a superconductor with a normal metal. A new derivation of the Lesovik-Levitov formulae is suggested. It is shown, for the S

Possible electron-phonon instabilities in two-dimensional Bloch-electron systems in magnetic fields
Autor: M A N Araujo, D E Khmelnitskii
Publikováno v: Journal of Physics: Condensed Matter. 6:8839-8852
The spectrum of a two-dimensional electron system in a square lattice potential subject to a perpendicular magnetic field is considered. Well known symmetry considerations show that if the magnetic field flux per unit cell (measured in units of the f
