We investigate the dynamics of quantum discord and concurrence between two excitonic qubits placed inside two coupled semiconductor quantum dots independently interacting with dephasing reservoirs. We explore their behavior against the dimensionless time and the temperature in both Markovian and non-Markovian environments. Moreover, we analyze the external electric field effects and the F\"orster interaction effects on these correlations. We show that, although the quantum correlations amount is strongly influenced by the variation of the electric field and the F\"orster interaction, their non-Markovian behavior is still preserved under the variation of these two parameters. Furthermore, we show that for large values of temperature and dimensionless time, unlike concurrence which vanishes, nonzero discord can still be observed.

两个耦合半导体 InAs 量子点中的量子相关动力学

我们研究了放置在两个耦合半导体量子点内的两个激子量子位之间的量子不协调和并发的动力学，这些量子位独立地与去相水库相互作用。我们探索了它们在马尔可夫和非马尔可夫环境中对无量纲时间和温度的行为。此外，我们分析了外部电场效应和 F\"orster 相互作用对这些相关性的影响。我们表明，虽然量子相关量受电场变化和 F\"orster 相互作用的影响很大，但它们的非-在这两个参数的变化下，马尔可夫行为仍然保留。此外，我们表明，对于大的温度值和无量纲时间，与消失的并发不同，仍然可以观察到非零不一致。
