| dc.description | Using our recently developed Chebyshev expansion technique for finite-temperature dynamical correlation functions we numerically study the AC conductivity $σ(ω)$ of the Anderson model on large cubic clusters of up to $100^3$ sites. Extending previous results we focus on the role of the boundary conditions and check the consistency of the DC limit, $ω\to 0$, by comparing with direct conductance calculations based on a Greens function approach in a Landauer Büttiker type setup. | |
