Abstract
The many-particle hopping problem in a one-component lattice gas of charged particles is investigated. A method is pointed out which allows the simultaneous treatment of correlations induced by the lattice and by the Coulomb interaction. Results are obtained for the concentration and temperature dependence of the tracer correlation factor and the quasielastic width of the incoherent scattering function. In addition, we discuss the long-wavelength charge fluctuation spectrum and possible anisotropy effects in layered systems.Keywords
