The topological invariants of a time-reversal-invariant band structure in two dimensions are multiple copies of the Z 2 invariant found by Kane and Mele. Such invariants protect the "topological insulator" phase and give rise to a spin Hall effect carried by edge states. Each pair of bands related b
