Opis:: New calculations of resistivities of liquid metals, Na, K, Rb, and alloys, Na-K, Na-Rb, K-Rb, were carried out by using a variant of the Kubo formula that explicitly contains the temperature T. The results come closer to the experiment than the previous ones that use the Ziman formula of resistivity.

Opis:: Calculations of the resistivity of liquid metals are performed basing on the structure factor a(q) which can be measured experimentally or calculated theoretically from the hard sphere model. The calculations are carried out by using the Ashcroft empty core pseudopotential in the framework of Ziman's formula along with different forms of the screening function due to Hartree, Geldart and Vosko, Hubbard, Overhauser, random phase approximation and self-consistent screening. The investigation is useful because it throws light on the importance of exchange and correlation effects in developing an appropriate description of the screening of ions by conduction electrons for calculating the resistivity of liquid metals.

Opis:: A local pseudopotential in the second-order perturbation theory is used to study the electron dispersion relation, the Fermi energy and deviation in the Fermi energy from free electron value for the liquid alkali metals. The influence of the five different forms of the local field correction functions on the aforesaid electronic properties is examined explicitly, which reflects the varying effects of screening. The depth of the first negative hump in the electron dispersion curves of the liquid alkali metals increases in the order Na, K, Rb, Cs.

Opis:: The Wills-Harrison pair interaction is investigated for liquid Fe on the base of the introduced relation between parameters of the model pseudopotential and d-electron characteristics. It is shown that the procedure suggested leads to the significant shift of the first minimum of the pair potential and increases the softness of its repulsive part.

Opis:: The bulk moduli of the Na-K, Na-Cs, and K-Rb liquid equiatomic alloys at T=373 K are calculated by the variational method with the hard-sphere reference system. The local Animalu-Heine model pseudopotential and Toigo-Woodruff exchange-correlation function are used for the calculation. A good agreement with experimental data is achieved.

Opis:: A summary is given of the minimum requirements posed by experimental results on a theory of copper-oxide metals and of the recent solution of a model of copper-oxygen bonding and anti-bonding bands with the most general two-body interactions allowable by symmetry which satisfies these requirements. Several experiments were proposed to test the theory.
