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…

Exact dimer ground states for a continuous family of quantum spin chains
M. Asoudeh, V. Karimipour, A. Sadrolashrafi
Using the matrix product formalism, we define a multi-parameter family of spin models on one dimensional chains, with nearest and next-nearest neighbor anti-ferromagnetic interacti…
