Unconventional Thermal and Magnetic-Field-Driven Changes of a Bipartite Entanglement of a Mixed Spin-(1/2,<i>S</i>) Heisenberg Dimer with an Uniaxial Single-Ion Anisotropy

The concept of negativity is adapted in order to explore the quantum and thermal entanglement of the mixed spin-(1/2,<i>S</i>) Heisenberg dimers in presence of an external magnetic field. The mutual interplay between the spin size <i>S</i>, XXZ exchange and uniaxial single-io...
