本研究提出通过在玻色子和费米子浴的谱密度中引入带隙来工程调控非马尔可夫性，数值模拟验证了该方法的有效性，为量子技术提供了新途径。
AI 中文摘要
非马尔可夫性是物理系统的未来状态依赖于其先前动力学历史的性质，即系统对其过去具有记忆。它是量子技术的关键资源，但在没有特定策略的情况下难以工程实现。在此，我们表明在玻色子和费米子浴的环境谱密度中引入带隙，为在宽范围内调节非马尔可夫性提供了直接途径。我们通过跨玻色子和费米子环境的数值模拟证明了这一效应，并讨论了我们的预测的实验测试。
英文摘要
Non-Markovianity is the property that a physical system's future state depends on its previous dynamical history, namely the system has memory of its past. It is a key resource for quantum technologies but it is difficult to engineer without specific strategies. Here, we show that introducing a band gap in the environmental spectral density of both bosonic and fermionic baths provides a direct route to tuning non-Markovianity over a wide range. We demonstrate this effect by means of numerical simulations across bosonic and fermionic environments and discuss experimental tests of our predictions.
