论文摘要
空间的各向同性不是逻辑要求,而是一个经验问题。确实有暗示性的证据表明宇宙可能是各向异性的。这些各向异性的合理来源可能是量子重力校正。如果这些校正恰好是电动量表和普朗克量表之间的,那么这些各向异性可以在短距离内产生可测量的后果,并且可以使用超敏感的冷凝物系统来测量其效果。我们研究了这种各向异性量子重力校正如何通过海森贝格代数的各向异性变形来改变低能物理。我们讨论如何使用扫描隧道显微镜观察到这种各向异性。
The isotropy of space is not a logical requirement but rather is an empirical question; indeed there is suggestive evidence that universe might be anisotropic. A plausible source of these anisotropies could be quantum gravity corrections. If these corrections happen to be between the electroweak scale and the Planck scale, then these anisotropies can have measurable consequences at short distances and their effects can be measured using ultra sensitive condensed matter systems. We investigate how such anisotropic quantum gravity corrections modify low energy physics through an anisotropic deformation of the Heisenberg algebra. We discuss how such anisotropies might be observed using a scanning tunneling microscope.
