Resumen:

We present numerical calculations for the density of states in the quantum percolation problem. A pseudogap is found at the center of the lower subband. This behavior is studied in two ways: first, by analyzing the first spectral moments, and second, by making a renormalization of the lattice. This shows that the pseudogap appears as a consequence of frustration effects in the renormalized sublattice. © 2005 by Imperial College Press. All rights reserved.
