Enthalpy-entropy compensation of atomic diffusion originates from softening of low frequency phonons

Atomistic diffusion in solids determines aging and the transformation of materials. Here, the authors resolve the origin of the ubiquitous enthalpy-entropy compensation effect, showing how it emerges from shifts in the vibrational modes of the materials during activation.
