摘要：
A real-space-renormalization method for the frequency dependent conductivity of the periodic approximants of the Fibonacci chain is developed. This scheme is based on the known 2×2 transfer matrices and additional 5×5 matrices which allow an efficient numerical evaluation of the Kubo formula. Numerical results are presented.
