AI 中文摘要
针对开放器件的实时量子电动力学密度泛函理论（QEDFT）需要局域电子与场的历史来确定其源。对于依赖占据数的相互作用及带隙有限带光子连续体，我们在非零时间区间的正向像上证明了因果性一一映射。三个源重构基准分别测试电子极限、光子连续体极限及耦合联合逆问题，针对闭式连续体端点开展，为实时开放系统QEDFT提供了密度-源基础。
英文摘要
Real-time quantum-electrodynamical density-functional theory (QEDFT) for an open device requires local electron and field histories to determine their sources. For occupation-dependent interactions and a gapped finite-band photon continuum, we prove a causal one-to-one map on the forward image over a nonzero time interval. Three source-reconstruction benchmarks test the electronic limit, the photon-continuum limit, and a coupled joint inverse against a closed-form continuum endpoint. This provides the density--source foundation for real-time open-system QEDFT.
