Title: Automorphic equivalence within gapped phases in the bulk
Abtract: Hastings's adiabatic method is a powerful tool in the analysis of gapped Hamiltonians in quantum spin systems. We develop a new adiabatic theorem for unique gapped ground states which requires a gap in the bulk and smoothness of expectation values of sub-exponentially localized observables in the unique gapped ground state. This talk is based on joint work with Yoshiko Ogata.
