The Earth's pole coordinates, obtained from satellite laser ranging data of Lageos-1 and Lageos-2 are presented. The procedure, used models and algorithms are described. Results are compared with similar series from IERS database.

We review recent results concerning the spectrum of edge states in the quantum Hall effect in graphene. In particular, a special attention is payed to the derivation of the conditions under which gapless edge states exist ...

This issue of “Condensed Matter Physics” is dedicated to the 100th anniversary of an outstanding personality of the XXth century, physicist and mathematician Mykola Bogolyubov (21.08.1909–13.02.1992).

In this issue of the journal “Condensed Matter Physics” we publish a part of Proceedings of the 2nd Ukrainian–Polish–Lithuanian Meeting on Ferroelectric Physics (UPL MFP-2). The meeting was held on September, 9–13, 2012 ...

An approach is proposed to obtain an effective Hamiltonian of a harmonically trapped Bose-system. Such a Hamiltonian is quadratic in the creation–annihilation operators and certain approximations allow to simplify higher ...

An additional magnetization damping for an inhomogeneous spin texture in metallic ferromagnets is calculated on the basis of the s–d exchange model. The effect of conduction electrons on the magnetization dynamics ...
