Abstract

We investigate the roles of different environmental models on quantum correlation decay behavior of a two-qubit composite system interacting with two independent environments. The most common environmental models (the single-Lorentzian model, the squared-Lorentzian model, the two-Lorentzian model and bandgap model) are analyzed. First, we note that, for the weak coupling regime, the monotonic decay speed of the quantum correlation is mainly determined by the spectral density functions of these different environments. Then, by considering the strong coupling regime we find that, contrary to what is stated in the weak coupling regime, the dynamics of quantum correlation primarily depends on the non-Markovianity of the environmental models.
