Right: Graphical sketch of the spiralling wavefronts typical for vortex waves. The wave can either spiral left or right handed. The central wave unlike the other waves is an ordinary spherical wave with not topological discontinuity along the beam axis.

Caption: This image demonstrates how with latest state of the art instrumentation, one can map the individual valence state of Mn atoms in a Mn3O4 crystal making use of subtle changes in the fine structure of the electron energy loss spectrum. The Mn atoms in Mn3O4 are ordered in a lattice of Mn2+ (green) and Mn3+ (red).
