Entanglement and coherence in a spin-s XXZ system under non-uniform fields

We investigate entanglement and coherence in an XXZ spin-s pair immersed in a non-uniform transverse magnetic field. The ground state and thermal entanglement phase diagrams are analyzed in detail in both the ferromagnetic and antiferromagnetic cases. It is shown that a non-uniform field enables to...
