  • Diagonal and off-diagonal types of disorder in condensed matter theory 
    Rudavskii, Yu.; Ponedilok, G.; Petriv, Yu. (Condensed Matter Physics, 2000)
    In the paper we investigate the distribution function of a diagonal type of disorder, their relation with microscopic model parameters and structural correlation functions. The conditions are obtained for which the ...
  • Long-wave spin excitations of crystalline s − d models 
    Rudavsky, Yu.; Ponedilok, G.; Dorosh, L. (Condensed Matter Physics, 1998)
    Long-wave spin excitations in the perfect s-d model are studied. The Hamiltonian of the model includes, apart from usually treated spin-electron processes, the Heisenberg exchange interaction of atomic spins and the ...
  • Model pseudopotential of the electron – negative ion interaction 
    Rudavskii, Yu.; Ponedilok, G.; Klapchuk, M. (Condensed Matter Physics, 2003)
    Generalization of the Anderson model to describe the states of electronegative impurities in liquid-metal alloys is the main aim of the present paper. The effects of the random inner field on the charge impurity states is ...
  • Some aspects of tight-binding approach in chemisorption theory 
    Rudavskii, Yu.; Ponedilok, G.; Petriv, Yu. (Condensed Matter Physics, 2001)
    The quantum-statistic problem of atoms chemisorption with hydrogen-like electronic structure on semiconductor and dielectric crystalline surfaces is considered. The superficial states are described in tight-binding ...
