Correlated Relation between Quantum Discord and Entanglement of Two-Atom in Thermal Reservoirs

Figure 2

Time dependence of quantum discord (dot-dashed line) and concurrence (solid line) for mean photon number: (a) 𝑛=1, (b) 𝑛=0.1, (c) 𝑛=0.01, and (d) 𝑛=0 (color online). The abscissa of the vertical dotted line corresponds to the scaled time 𝛾𝑡^′ of the intersection point of the two evolution curves.
