Automorphic equivalence within gapped phases in the bulk
Alvin Moon, Yoshiko Ogata
We develop a new adiabatic theorem for unique gapped ground states which does not require the gap for local Hamiltonians. We instead require a gap in the bulk and a smoothness of e…

A -index of symmetry protected topological phases with reflection symmetry for quantum spin chains
Yoshiko Ogata
For the classification of SPT phases, defining an index is a central problem. In the famous paper [PTBO1], Pollmann, Tuner, Berg, and Oshikawa introduced -indices fo…
