Improved recursive Green's function formalism for quasi one-dimensional systems with realistic defects

With the improved recursive Green's function formalism + renormalization decimation algorithm (RGF+RDA), the conductance of mesoscopic systems with realistic defects can be computed much faster than with the common RGF. For a constant system length, the calculation time t scales logarithmically with the number of defects ND. This is true for the recursive decimation scheme (RDS) as well as for the forward iteration scheme (FIS).
