Abstract
The problem of screening of local moments in a metallic environment is revisited, in the context of quasiperiodic solids. The motivation for this study comes from experimental studies showing that low temperature thermodynamic properties are strongly anomalous in the quasicrystalline phase, but less or not anomalous in the related approximant phase. A model for a magnetic impurity in a quasiperiodic environment is introduced and solved numerically. Arguments are given for the existence of a singular distribution of Kondo temperatures in the quasicrystal, thereby providing a possible explanation for the experimental observations.
