  An extensive numerical analysis of the scattering and transport properties of
the power-law banded random matrix model (PBRM) at criticality in the presence
of orthogonal, unitary, and symplectic symmetries is presented. Our results
show a good agreement with existing analytical expressions in the metallic
regime and with heuristic relations widely used in studies of the PBRM model in
the presence of orthogonal and unitary symmetries. Moreover, our results
confirm that the multifractal behavior of disordered systems at criticality can
be probed by measuring scattering and transport properties, which is of
paramount importance from the experimental point of view. Thus, a full picture
of the scattering and transport properties of the PBRM model at criticality
corresponding to the three classical Wigner-Dyson ensembles is provided.
