What is it about?
Mean squared displacement of ions in ionically conducting glasses shows nealy constant region (NCL) before occuring of jump motion of ions. Such region becomes longer and longer with lowering temperature. Characteristics of motions in the cage was characterized by molecular dynamics simulations.

Why is it important?
The dynamics of ions in the NCL region are characterized by anharmonic motions within cages, and from which the NCL originates. Moreover, the dynamics shows strong intermittency. Similar behaviors to the NCL is also found in glass forming liquids and therefore characterization of caging behaviors is also useful for better understanding of the glass transition.
