## Abstract Based on __ab initio__ energies and forces we construct an effective Hamiltonian for anharmonic dynamics of potassium cations in the __Ξ²__ ‐pyrochlore compound KOs~2~O~6~. We solve numerically the single‐site problem which is characterized by an extremely flat potential well allowing fo
