Topological Hopf-Chern Insulators and the Hopf Superconductor
Ricardo Kennedy
We introduce new three-dimensional topological phases of two-band models using the Pontryagin-Thom construction. In symmetry class A these are the infinitely many Hopf-Chern topolo…

Bott-Kitaev Periodic Table and the Diagonal Map
R. Kennedy, M. R. Zirnbauer
Building on the 10-way symmetry classification of disordered fermions, the authors have recently given a homotopy-theoretic proof of Kitaev's "Periodic Table" for topological insul…

Homotopy Theory of Strong and Weak Topological Insulators
Ricardo Kennedy, Charles Guggenheim
We use homotopy theory to extend the notion of strong and weak topological insulators to the non-stable regime (low numbers of occupied/empty energy bands). We show that for strong…
