A Comment on the Relation between Diffraction and Entropy

A Comment on the Relation between Diffraction and Entropy

Diffraction methods are used to detect atomic order in solids. While uniquely ergodic systems with pure point diffraction have zero entropy, the relation between diffraction and entropy is not as straightforward in general. In particular, there exist families of homometric systems, which are systems...
