AI 中文摘要
本文采用计算量子场论（CQFT）研究了束缚态在惯性参考系间的相对论动力学，结果表明给定势阱内束缚态的时空性质严格依赖于参考系。关键在于，外场的这种时空调制可降低真空正负电子对产生所需的激光强度阈值。解析与数值计算显示，该阈值降低源于四动量的洛伦兹变换，其会重塑相空间中的真空激发路径。通过发展CQFT，本文建立了一个综合框架，其中相对论效应本质上主导着量子真空衰变过程。
英文摘要
The relativistic dynamics of bound states across inertial reference frames are investigated using the computational quantum field theory (CQFT). The results reveal that the spatiotemporal properties of bound states within a given potential well are strictly frame-dependent. Crucially, this spatiotemporal modulation of the external field enables a reduction in the laser intensity threshold required for vacuum electron-positron pair creation. Analytical and numerical calculations demonstrate that this threshold reduction originates from the Lorentz transformation of the four-momentum, which reshapes the vacuum excitation pathways in phase space. By developing CQFT, we establish a comprehensive framework in which relativistic effects intrinsically govern the quantum vacuum decay process
