  "abstract": "Using our recently developed Chebyshev expansion technique for finite-temperature dynamical correlation functions we numerically study the AC conductivity $\\sigma(\\omega)$ 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, $\\omega\\to 0$, by comparing with direct conductance calculations based on a Greens function approach in a Landauer B\\\"uttiker type setup.",
