According to the heuristic argument by Harris, uncorrelated disorder is irrelevant when the specific heat critical exponent $\\alpha$ is negative, which is the case for the pure $^4$He. However, experiments on helium in aerogel\n have shown that the superfluid density critical exponent $\\zeta$ changes. We hypothesize that this is a cross-over effect due to the fractal nature of aerogel. Modelling the aerogel as an incipient percolating cluster","authors_text":"K. Moon, S. M.
