✦ Synopsis
Scattering of electrons due to fractons can result in a resistivity that decreases with temperature. Such a behavior also appears in real quasicrystalline materials. If this is then attributed to effective fracton scattering, fracton-superconductivity would be theoretically possible. By fitting with the scattering result the experimental resistivity data for the AlPdMn quasicrystal, we estimate the corresponding T . This effective fracton interpretation, not unexpected for a self-similar system, c is also found consistent with other experiments on thermal and acoustic properties of the AlPdMn quasicrystal.
