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 Shaniv et al (2018 Phys. Rev. Lett. 120 103202). 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.

局部洛伦兹对称性违反和爱因斯坦等价原理

洛伦兹对称违反(LV)最近被提出可以用一种新方法进行测试,其中违反的影响被描述为某种局部相互作用Shaniv等人(2018 Phys.Rev.Lett.120103202)。我们在论文中重新审视了这种LV效应,并表明它不仅是局部的,而且根据爱因斯坦当量原理(EEP)的最新量子公式,它也代表了经典的违反。在谐波陷获的自旋1/2原子系统的基础上,我们将通过测试LV效应的台式实验结果来估计EEP量子公式中的相应违反参数。我们发现违反参数确实很小,这是早期理论估计所期望的。
