Precision tests of fundamental physics at the electroweak unification scale

该项目旨在通过在低温下实施蓝宝石和石英体声波谐振器及相关技术，推动新的精密频率产生和测量技术的发展，超越目前的技术水平。该项目计划将这一技术进步应用到对广义相对论的极其敏感的测试中，从而能够探测普朗克尺度发出的被抑制的效应。这些测试包括光子和声子的洛伦兹不变性破坏的新测试，基本常量不变性测试和其他基础物理测试。这些结果可能会导致发现正确的量子引力理论，这是当代物理学中一个尚未解决的主要问题。

The project aims to advance novel precision frequency generation and measurement techniques beyond the present state of the art, through the implementation of sapphire and quartz bulk acoustic wave resonator and related technology at low temperature. The project plans to apply this technological advancement to extremely sensitive tests of General Relativity able to probe suppressed effects emanating from the Planck scale. Such tests include new tests of Lorentz invariance violations of photons and phonons, tests of fundamental constant invariance and other tests of fundamental physics. Results could lead to the discovery of the correct theory of quantum gravity, a major unsolved problem in contemporary physics.
