From symmetry-protected topological order to Landau order | | Kasper Duivenvoorden

26 Apr 2013 | | Abstract: | Focusing on the particular case of the discrete symmetry group Z_N x Z_N, we
establish a mapping between symmetry protected topological phases and symmetry
broken phases for one-dimensional spin systems. It is realized in terms of a
non-local unitary transformation which preserves the locality of the
Hamiltonian. We derive the image of the mapping for various phases involved,
including those with a mixture of symmetry breaking and topological protection.
Our analysis also applies to topological phases in spin systems with arbitrary
continuous symmetries of unitary, orthogonal and symplectic type. This is
achieved by identifying suitable subgroups Z_N x Z_N in all these groups,
together with a bijection between the individual classes of projective
representations. | | Source: | arXiv, 1304.7234 | | Services: | Forum | Review | PDF | Favorites | |
