论文摘要
我们研究了两个耦合的半导体量子点在与dephasing储层独立相互作用的两个耦合的半导体量子点内，量子不和谐和同步的动力学。我们探索了他们在马尔可夫和非马克维亚环境中的无量纲时间和温度上的行为。此外，我们分析了外部电场效应以及对这些相关性的Förster相互作用效应。我们表明，尽管量子相关量受到电场的变化和förster相互作用的强烈影响，但它们的非马克维亚行为仍然保留在这两个参数的变化下。此外，我们表明，对于大量的温度和无量纲时间值，与消失的同意不同，仍然可以观察到非零的不和谐。
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 Förster 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 Förster 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.
