用慢原子探测量子引力领域
Probing the quantum-gravity realm with slow atoms
摘要:
为了研究能量-动量色散关系的普朗克尺度修正,我们考虑了涉及非相对论性粒子,特别是原子的实验的可能作用。我们扩展了最近的结果,建立“原子反冲频率”的测量可以提供一些有价值的理论模型的见解。并从更广的视角分析了非相对论和超相对论两种体系在这一研究领域的互补性。
英文摘要:
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.
