Query: Transport in tight-binding bond percolation models   Most of the investigations to date on tight-binding, quantum percolation
models focused on the quantum percolation threshold, i.e., the analogue to the
Anderson transition. It appears to occur if roughly 30% of the hopping terms
are actually present. Thus, models in the delocalized regime may still be
substantially disordered, hence analyzing their transport properties is a
nontrivial task which we pursue in the paper at hand. Using a method based on
quantum typicality to numerically perform linear response theory we find that
conductivity and mean free paths are in good accord with results from very
simple heuristic considerations. Furthermore we find that depending on the
percentage of actually present hopping terms, the transport properties may or
may not be described by a Drude model. An investigation of the Einstein
relation is also presented.
