Symmetry protected topological phases beyond groups: The q-deformed AKLT model | Thomas Quella
; | Date: |
18 May 2020 | Abstract: | We argue that the $q$-deformed spin-1 AKLT Hamiltonian should be regarded as
a representative of a symmetry protected topological phase. Even though it
fails to exhibit any of the standard symmetries known to protect the Haldane
phase it still displays all characteristics of this phase: Fractionalized
spin-$frac{1}{2}$ boundary spins, non-trivial string order and -- when using
an appropriate definition -- a two-fold degeneracy in the entanglement
spectrum. We trace these properties back to the existence of an $SO_q(3)$
quantum group symmetry and speculate about potential links to discrete duality
symmetries. We expect our findings and methods to be relevant for the
identification, characterization and classification of other symmetry-protected
topological phases with non-standard symmetries. | Source: | arXiv, 2005.9072 | Services: | Forum | Review | PDF | Favorites |
