Experimental Evidence for Quantum Spin Hall Effect

A new report published in Science this week presents compelling evidence that verify the existence of the quantum spin Hall effect[1]. It appears that they have achieved something similar to a "dissipationless flow" of the spin current.

This is touted as being a crucial step in spintronics.
