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

Defined a Z2 topological invariant for time-reversal-invariant Hamiltonians, distinguishing the quantum spin Hall phase from an ordinary insulator and extending the classification beyond a two-band graphene model.

What is recorded here?

Defined a Z2 topological invariant for time-reversal-invariant Hamiltonians, distinguishing the quantum spin Hall phase from an ordinary insulator and extending the classification beyond a two-band graphene model.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

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.
