Exact symmetry breaking ground states for quantum spin chains
S. Alipour, S. Baghbanzadeh, V. Karimipour
We introduce a family of spin-1/2 quantum chains, and show that their exact ground states break the rotational and translational symmetries of the original Hamiltonian. We also sho…

Entanglement and quantum phase transitions in matrix product spin one chains
S. Alipour, V. Karimipour, L. Memarzadeh
We consider a one-parameter family of matrix product states of spin one particles on a periodic chain and study in detail the entanglement properties of such a state. In particular…
