Suppression of anharmonic phonons and s-wave superconductivity by defects in the filled skutterudite LaRu_{4}As_{12}

In filled-skutterudite compounds, guest atoms are centered at highly symmetric cages essentially formed by pnictogens. The weak bonding of the guest atoms to the cage-forming elements is expected to give rise to local atomic vibrations in anharmonic potential which can influence electronic propertie...
