论文摘要
产生能量和势头的时间和空间不变性不仅是物理学中最基本的对称性假设，而且是最普遍接受的对称性假设。然而，对实验和观察性测试进行此类假设是谨慎的。在本说明中，我们朝这个方向迈出了第一步，指定了一个简单的定期时间依赖性，违反了QED中的时间翻译，并在其上设置了现象学约束。除了在变化的耦合上的观察性和实验限制外，我们还专注于违反能量守恒的探针，例如自发产生光子和电子对以及$ e \ toeγ$工艺。我们讨论了与时间变化的基本常数的讨论以及光玻色子暗物质领域的相似性和差异，通常也会引起振荡效果。
Time and space translation invariance, giving rise to energy and momentum conservation, are not only amongst the most fundamental but also the most generally accepted symmetry assumptions in physics. It is nevertheless prudent to put such assumptions to experimental and observational tests. In this note, we take the first step in this direction, specifying a simple periodic time dependence that violates time translation invariance in QED, and setting phenomenological constraints on it. In addition to observational and experimental constraints on time varying couplings, we focus on probes of violation of energy conservation such as spontaneous production of photon and electron pairs and the $e \to e γ$ process. We discuss similarities and differences to the discussion of time varying fundamental constants and to the case of a light bosonic dark matter field that usually also causes oscillating effects.
