Abstract
Using orthogonal polynomials, a novel approach for studying DC and AC conductivity and
velocity-velocity correlation function has been developed. The method works in direct space and can
treat order or disordered, finite or infinite, and pure or alloy systems with equal ease. Further,
it is not computer intensive and allows conductivity calculations as a function of frequency or the
location of the Fermi energy in an efficient manner.
