Abstract
The critical behaviour of the bond-diluted two-dimensional quantum transverse Ising model is investigated by an approximate cluster decimation transformation. The dependence of the critical field on the concentration shows a discontinuity at the percolation concentration, associated with the existence of long-range order in the percolating cluster at non-zero transverse field, according to Harris' conjecture (1974).Keywords
