We review the question of whether the fundamental laws of nature limit our ability to probe arbitrarily short distances. First, we examine what insights can be gained from thought experiments for probes of shortest distances, and summarize what can be learned from different approaches to a theory of quantum gravity. Then we discuss some models that have been developed to implement a minimal length scale in quantum mechanics and quantum field theory. These models have entered the literature as the generalized uncertainty principle or the modified dispersion relation, and have allowed the study of the effects of a minimal length scale in quantum mechanics, quantum electrodynamics, thermodynamics, black-hole physics and cosmology. Finally, we touch upon the question of ways to circumvent the manifestation of a minimal length scale in short-distance physics.

量子引力的最小长度尺度方案。

我们回顾一下自然的基本定律是否限制了我们探测任意短距离的能力的问题。首先，我们研究从思想实验中获得最短距离的探针可以获得哪些见解，并总结从不同的量子引力理论方法中可以学到的知识。然后，我们讨论一些已开发出来的用于在量子力学和量子场论中实现最小长度尺度的模型。这些模型作为广义不确定性原理或修正的色散关系进入了文献，并允许研究最小长度尺度对量子力学，量子电动力学，热力学，黑洞物理学和宇宙学的影响。最后，
