Kane and Mele: Z2 topological order and the quantum spin Hall effect

What changed

A robust topological distinction for 2D time-reversal-invariant insulators became available.

Scientific scope

Exact 2005 two-author PRL; companion graphene proposal, 3D theory and experiments separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 2005 Physical Review Letters paper. The companion graphene proposal, later three-dimensional topological-insulator theory, material predictions, experimental realizations and subsequent classifications remain separate.
