Query: Nonequilibrium Effects on Quantum Correlations: Discord, Mutual
  Information and Entanglement of a Two-Fermionic System in Bosonic and
  Fermionic Environments   We study the steady state entanglement and correlations of an open system
comprised of two coupled fermions in the equilibrium or nonequilibrium
environments and distill the nonequilibrium contribution to the quantum
correlations. We show that in the equilibrium condition, the steady-state
quantum correlations exhibit non-monotonic behavior, while in the
nonequilibrium case, the monotonicity is determined by many parameters. The
entanglement vanishes abruptly upon the increase of the temperature (bias) and
chemical potential bias, it witnesses a critical chemical potential above which
the concurrence always remains positive. In the fermionic reservoirs, quantum
correlations reach the maximal values when one chemical potential of the
reservoirs matches to the system frequency. We separate the quantum correlation
generation due to the averaged effect from the pure nonequilibrium effect. In
contrast with the previous results, when the averaged effect is separated out,
the nonequilibrium generation of quantum correlation shows a distinctive
monotonic behavior. The difference between the large-tunneling regime with
decaying correlations and the small-tunneling with increasing correlations is
discussed. Near the boundary of the two regimes, the entanglement behavior is a
mixture of two extremes, it resurrects with the increase of chemical potential
bias after its previous drop to zero.
