Topological edge states in two-dimensional $Z_{4}$ Potts paramagnet protected by the $Z_{4}^{\times 3}$ symmetry

Hrant Topchyan, Tigran Hakobyan, Mkhitar Mirumyan +2

We construct a two-dimensional bosonic symmetry-protected topological (SPT) paramagnet protected by an on-site $G = Z_{4}^{\times 3}$ symmetry, starting from a three-component…

Two-dimensional topological paramagnets protected by $Z_{3}$ symmetry: Properties of the boundary Hamiltonian

Hrant Topchyan, Vasilii Iugov, Mkhitar Mirumyan +3

We systematically study gapless edge modes corresponding to $Z_{3}$ symmetry-protected topological (SPT) phases of two-dimensional three-state Potts paramagnets on a triangu…
