Topological effects in nanomagnetism: from superparamagnetism to chiral quantum solitons (Baun) (very good discussion about topology in the introduction)
Model for a Quantum Hall Effect without Landau Levels: Condensed-Matter Realization of the "Parity Anomaly" (Haldane)
Z2 Topological Order and the Quantum Spin Hall Effect (Kane, Mele)
Colloquium: Topological insulators (Hasan , Kane)
Read in order. There are also various books in the subject from good authors like Bernevig, Kane, ...etc.
