论文摘要
普遍的不确定性原理（GUP）和独立的洛伦兹对称性违规是许多量子重力理论的两个共同特征。尽管如此，到目前为止，两者之间的重叠受到了有限的关注。在这篇简短的论文中，我们对此主题进行了进一步的调查。在非同性主义级别和换向时空坐标的领域中，显示了一大批以及各向异性的GUP模型在实验上与标准模型扩展（SME）（SME）（SME）（用于研究Lorentz-Violents-Violation fenomena以外的常见框架）产生信号。该标识用于使用中小企业系数的当前限制来限制GUP模型。特别是，与当前的光谱界相比，各向同性GUP模型的界限提高了$ 10^{7} $，并且第一次限制了各向异性模型。
Generalized uncertainty principles (GUP) and, independently, Lorentz symmetry violations are two common features in many candidate theories of quantum gravity. Despite that, the overlap between both has received limited attention so far. In this brief paper, we carry out further investigations on this topic. At the nonrelativistic level and in the realm of commutative spacetime coordinates, a large class of both isotropic and anisotropic GUP models is shown to produce signals experimentally indistinguishable from those predicted by the Standard Model Extension (SME), the common framework for studying Lorentz-violating phenomena beyond the Standard Model. This identification is used to constrain GUP models using current limits on SME coefficients. In particular, bounds on isotropic GUP models are improved by a factor of $10^{7}$ compared to current spectroscopic bounds and anisotropic models are constrained for the first time.
