Abstract
The dc conductivity for a tight-binding Hamiltonian on a two-dimensional Penrose lattice is computed numerically for finite systems from Kubo’s formula using the recursion method. Results are suggestive of a weak metallic behavior where states are more localized than in the case of a pure crystal, in agreement with recent conjectures by Sutherland.Keywords
