The correlations, entanglement entropy, and fidelity susceptibility arecalculated for a one-dimensional spin-1/2 XXZ chain with anisotropic power-lawlong range interactions by employing the density matrix renormalization groupmethod. In particular, this long-range interaction is assigned to ferromagneticfor transversal components, while it can be either ferro- or antiferromagneticfor the longitudinal spin component. Two ground-state phase diagrams areestablished versus the anisotropy of the interactions which not only changesthe phase boundaries of the counterparts with short-range interactions, butalso leads to the emergence of exotic phases. We found that the long-rangeinteractions of the z-component results in a Wigner crystal phase, whereas thetransversal one may break a continuous symmetry, resulting in a continuoussymmetry breaking phase.
