论文摘要
洛伦兹对称违规（LV）最近被提议使用一种新方法进行测试，其中违法的效果被描述为某种局部相互作用[R. Shaniv等人，PRL 120，103202（2018）]。我们在本文中重新审视了这种LV效应，并表明它不仅是局部的，而且还代表了根据爱因斯坦等效原理（EEP）的最新量子表述（EEP）的经典违规行为。基于谐波捕获的自旋1/2原子系统，我们应用表顶实验测试LV效应的结果来估计EEP量子公式中相应的违规参数。我们发现，违规参数确实很小，正如早期的理论估计所预期的那样。
Lorentz symmetry violation (LV) was recently proposed to be testable with a new method, in which the effect of the violation is described as a certain local interaction [R. Shaniv, et al, PRL 120, 103202 (2018)]. We revisit this LV effect in the paper and show that it is not only local, but it also represents a classical violation according to the recent quantum formulation of the Einstein equivalence principle (EEP). Based on a harmonically trapped spin-1/2 atomic system, we apply the results of table-top experiments testing LV effect to estimate the corresponding violation parameter in the quantum formulation of EEP. We find that the violation parameter is indeed very small, as expected by the earlier theoretical estimation.
