Asymmetric steerability of quantum equilibrium and nonequilibrium steady states through entanglement detection
Kun Zhang, Jin Wang
Einstein-Podolsky-Rosen steering describes a quantum correlation in addition to entanglement and Bell nonlocality. However, conceptually different from entanglement and Bell nonloc…

Entanglement versus Bell nonlocality of quantum nonequilibrium steady states
Kun Zhang, Jin Wang
We study the entanglement and the Bell nonlocality of a coupled two-qubit system, in which each qubit is coupled with one individual environment. We study how the nonequilibrium en…

Influence of equilibrium and nonequilibrium environments on macroscopic realism through the Leggett-Garg inequalities
Kun Zhang, Wei Wu, Jin Wang
We study the macroscopic realism (macrorealism) through the two- and three-time Leggett-Garg inequalities (LGIs) in a two interacting qubits system. The two qubits are coupled eith…
