A class of asymmetric gapped Hamiltonians on quantum spin chains and its characterization I
Yoshiko Ogata
We introduce a class of gapped Hamiltonians on quantum spin chains, which allows asymmetric edge ground states. This class is an asymmetric generalization of the class of Hamiltoni…

A class of asymmetric gapped Hamiltonians on quantum spin chains and its characterization II
Yoshiko Ogata
We give a characterization of the class of gapped Hamiltonians introduced in PartI [O]. The Hamiltonians in this class are given as MPS (Matrix product state) Hamiltonians. In [O],…
