Topological edge states in two-dimensional Potts paramagnet protected by the symmetry
Hrant Topchyan, Tigran Hakobyan, Mkhitar Mirumyan +2
We construct a two-dimensional bosonic symmetry-protected topological (SPT) paramagnet protected by an on-site symmetry, starting from a three-component…
Two-dimensional topological paramagnets protected by symmetry: Properties of the boundary Hamiltonian
Hrant Topchyan, Vasilii Iugov, Mkhitar Mirumyan +3
We systematically study gapless edge modes corresponding to symmetry-protected topological (SPT) phases of two-dimensional three-state Potts paramagnets on a triangu…
and symmetry protected topological paramagnets
Hrant Topchyan, Vasilii Iugov, Mkhitar Mirumyan +3
We identify two-dimensional three-state Potts paramagnets with gapless edge modes on a triangular lattice protected by symmetry and s…
Integrable XYZ Model with Staggered Anisotropy Parameter
D. Arnaudon, D. Karakhanyan, M. Mirumyan +2
We apply to the XYZ model the technique of construction of integrable models with staggered parameters, presented recently for the XXZ case. The solution of modified Yang-Baxter eq…
Universal R operator with deformed conformal symmetry
D. Karakhanyan, R. Kirschner, M. Mirumyan
We study the general solution of the Yang-Baxter equation with deformed symmetry. The universal R operator acting on tensor products of arbitrary representations is obtaine…
Fermionisation of the Spin-S Uimin-Lai-Sutherland Model: Generalisation of Supersymmetric t-J Model to Spin-S
J. Ambjorn, D. Karakhanyan, M. Mirumyan +1
The spin-1 Uimin-Lai-Sutherland (ULS) isotropic chain model is expressed in terms of fermions and the equivalence of the fermionic representation to the supersymmetric t-J model is…
