Abstract
In a solid, electrons behave differently than in a vacuum. In particular, their charge can break up into fractions of the elementary charge. Theoretical work shows how the electron's spin could help to observe fractional charges directly.

Topological insulators are band insulators in which spin?orbit coupling takes the role of the applied magnetic field in the integer quantum Hall effect. Theory now predicts that dislocations in such systems can give rise to one-dimensional topologically protected states, resembling helical modes at the edge of a two-dimensional quantum spin Hall insulator.
