Theoretical studies of processes involving implanted muons

Recent advances in the theoretical study of implanted muons in solids include progress in quantitative modelling of the energetics of binding sites taken up by the muon after implantation. In the last two years, the range of materials that has been studied has grown from simple elemental crystals to complex molecular materials; path-integral methods have also been introduced to study the quantum-mechanical effects arising from the light mass of the muon.
