Chemical Density Functional Theory for dense Coulomb plasmas

The Chemical Density Functional Theory (CDFT) is proposed as a new model for nonideal plasmas of nuclei and electrons in thermodynamical equilibrium. It is based on a DFT-like treating on the microscopic level assuming the existence of chemical species (chemical picture). This is embedded in a thermodynamical level which is spanned up by the large-distance limits of the distribution functions. The effects of inhomogeneity are taken into account which are important for the pressure ionization. Both levels of description are coupled via certain quantities. (orig.)
