  Quantum resources, such as entanglement, steering, and Bell nonlocality, are
evaluated for three coupled qubits in the steady-state configuration, which is
calculated by employing the phenomenological and the microscopic models. We
show that the quantum resources obtained by these two models give different
results. In particular, steering and Bell nonlocality are null within the
phenomenological model, while they reach considerable values within the
microscopic model. These results show that the phenomenological approach is not
able to capture all quantum resources of the system. We also provide an
analytical expression for the steady-state of the system composed of three
coupled qubits in the zero temperature limit.
