Screw dislocations play an important role in materials’ mechanical, electrical and optical properties. However, imaging the atomic displacements in screw dislocations remains challenging. Although ...

The relaxed state of a type of topological defect (screw dislocation) located in a dispersive (non-local) elastic solid is discussed from a viewpoint of gauge field theory. The starting point of this ...
