Projector augmented waveAs the foundation for a new computational implementation, we survey the calculation of the complex electrical conductivity tensor based on the Kubo-Greenwood (KG) formalism (Kubo, 1957; Greenwood, 1958), with emphasis on derivations and technical aspects pertinent to use of ...
We discuss the foundations and extend the range of applicability of the widely used Kubo-Greenwood formula (KGF) for the electronic conductivity. The conductivity is derived from the current density, and only the probability amplitude rather than the transition probability is used. It is shown that...
Currently, the most common method to calculate transport properties for materials under extreme conditions is based on the phenomenological Kubo-Greenwood method. The results of an inquiry into the justification and context of that model are summarized here. Specifically, the basis for its connection ...
The static Kubo-Greenwood conductivity is analysed for different orders of the thermodynamic and zero-frequency limits. Firstly, the physically proper order of limits is studied by calculating the zero-frequency limit of an integrated dynamical conductivity after taking the thermodynamic limit. Secondly,...

We present a calculation of Seebeck coefficient derived by Kubo-Greenwood formula with the density functional theory. The electronic structure calculation being the Korringa-Kohn-Rsestoker Green's function method with coherent potential approximation and local density functional method (KKR-CPA-LDA). We...
