Conductance of a penrose tiling

Abstract
The conductance of a tight-binding model on a Penrose tiling is calculated as a function of Fermi energy by the multichannel Landauer formula. The conductance shows spiky fine structures. The behavior of the conductance is compared with the density of states of the corresponding system. It is also found that the dependence of the conductance on the system size is anomalous and analogous to the universal conductance fluctuation.
