摘要：

在本文中，我们研究了一个新的含义不可忽略的时空曲率在大的距离时，其影响表示在一个适当的修改形式的海森堡不确定性关系。具体来说，我们建立了一个一对一的对应关系，这种修改的不确定原理和标准模型扩展（SME），弦理论的有效场论，占显式和自发破缺的洛伦兹对称性。弦导出的有效场论和具有扩展不确定关系的修正量子力学之间的这种紧密对应性通过比较两个模型导出的变形霍金温度的预测得到了验证。此外，从实验上的中小企业的重力部门的界限，我们得到了迄今为止最严格的限制自由参数的值进入扩展海森堡不确定原理。

英文摘要：

In this paper, we investigate a novel implication of the non-negligible spacetime curvature at large distances when its effects are expressed in terms of a suitably modified form of the Heisenberg uncertainty relations. Specifically, we establish a one-to-one correspondence between such modified uncertainty principle and the Standard Model Extension (SME), a string-theoretical effective field theory that accounts for both explicit and spontaneous breaking of Lorentz symmetry. This tight correspondence between string-derived effective field theory and modified quantum mechanics with extended uncertainty relations is validated by comparing the predictions concerning a deformed Hawking temperature derived from the two models. Moreover, starting from the experimental bounds on the gravity sector of the SME, we derive the most stringent constraint achieved so far on the value of the free parameter entering in the extended Heisenberg uncertainty principle.
