A class of asymmetric gapped Hamiltonians on quantum spin chains and its characterization III
Yoshiko Ogata
In this paper, we consider classification problem of asymmetric gapped Hamiltonians, which are given as the non-degenerate part of the Hamiltonians introduced in [O1]. We consider…

C^1-Classification of gapped parent Hamiltonians of quantum spin chains with local symmetry
Yoshiko Ogata
We consider the family of gapped Hamiltonians introduced in [FNW] on the quantum spin chains , with local symmetry given by a…
