Topological phases: isomorphism, homotopy and -theory
Guo Chuan Thiang
Equivalence classes of gapped Hamiltonians compatible with given symmetry constraints, such as those underlying topological insulators, can be defined in many ways. For the non-chi…

On the K-theoretic classification of topological phases of matter
Guo Chuan Thiang
We present a rigorous and fully consistent -theoretic framework for studying gapped topological phases of free fermions such as topological insulators. It utilises and profits f…
