标题： Probing the quantum-gravity realm with slow atoms

摘要： 对于研究普朗克尺度对能量-动量色散关系的修改，此前的研究主要集中在对超相对论性（超高速）粒子的影响上，我们考虑了涉及非相对论性粒子，特别是原子的实验可能起到的作用。 我们扩展了一个最近的结果，该结果表明，“原子反冲频率”的测量可以为某些理论模型提供有价值的见解。 从更广泛的角度来看，我们分析了这一研究领域中非相对论性和超相对论性 regimes 的互补性。 显示英文摘要

摘要： For the study of Planck-scale modifications of the energy-momentum dispersion relation, which had been previously focused on the implications for ultrarelativistic (ultrafast) particles, we consider the possible role of experiments involving nonrelativistic particles, and particularly atoms. We extend a recent result establishing that measurements of "atom-recoil frequency" can provide insight that is valuable for some theoretical models. And from a broader perspective we analyze the complementarity of the nonrelativistic and the ultrarelativistic regimes in this research area.
