Abstract:The original motivation of great interest to topological insulators was the hope to observe the quantum spin Hall effect. Therefore if a material is in the topological insulator state they frequently call it the quantum spin Hall state. However, despite impressive experimental results confirming the existence of the quantum spin Hall STATE, the quantum spin Hall EFFECT has not yet been detected. After an introduction addressing topological insulators and the spin Hall effect, I shall discuss whether and how the quantum spin Hall effect could be observed.
