- Abstract: We examine the Dzyaloshinski-Moriya (DM) and
Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEA) interactions in thermal
equilibrium submitted to the anisotropic Heisenberg two-qubit model in an
inhomogeneous magnetic field. The steerability between the two qubits is
evaluated using quantum steering. The concurrence serves as a witness to
quantum entanglement. Both the extracted work and the ideal efficiency of the
two qubits are quantified. We discuss how quantum correlations behave in
relation to the bath's temperature and the
Kaplan-Shekhtman-Entin-Wohlman-Aharony coupling parameter. We find that the
nonclassical correlations in a two-qubit Heisenberg XYZ Model are fragile under
thermal effects. Nevertheless, the results indicate that the concurrence is
stronger than quantum steering under thermal effects. We obtained that an
extraction of work is comparable with the bare energies.

The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels.
Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.

We introduce a quantum version for the statistical complexity measure, in the context of quantum information theory, and use it as a signalling function of quantum order-disorder transitions.
We apply our measure to two exactly solvable Hamiltonian models, namely: the $1D$-Quantum Ising Model and the Heisenberg XXZ spin-$1/2$ chain.
We also compute this measure for one-qubit and two-qubit reduced states for the considered models, and analyse its behaviour across its quantum phase transitions for finite system sizes as well as in the thermodynamic limit by using Bethe ansatz.
