Heisenberg XYZ Hamiltonian with integrable impurities

A Hamiltonian of the impurity model is constructed within the framework of the open boundary Heisenberg XYZ spin chain. This impurity model is exactly solvable and degenerates to the integrable XXZ impurity model in the triangular limit. This approach is the first to add the integrable impurities to the completely anisotropic Heisenberg spin model with open boundary conditions.
