  bibo_abstract:
  - Several realistic spin-orbital models for transition metal oxides go beyond the
    classical expectations and could be understood only by employing the quantum entanglement.
    Experiments on these materials confirm that spin-orbital entanglement has measurable
    consequences. Here, we capture the essential features of spin-orbital entanglement
    in complex quantum matter utilizing 1D spin-orbital model which accommodates SU(2)⊗SU(2)
    symmetric Kugel-Khomskii superexchange as well as the Ising on-site spin-orbit
    coupling. Building on the results obtained for full and effective models in the
    regime of strong spin-orbit coupling, we address the question whether the entanglement
    found on superexchange bonds always increases when the Ising spin-orbit coupling
    is added. We show that (i) quantum entanglement is amplified by strong spin-orbit
    coupling and, surprisingly, (ii) almost classical disentangled states are possible.
    We complete the latter case by analyzing how the entanglement existing for intermediate
    values of spin-orbit coupling can disappear for higher values of this coupling.@eng
