If the same precision could be achieved with antihydrogen, a comparison of the two spectra would take physics well beyond the present CPT frontier for stable particles.

我们已经有非常精确的氢原子光谱，如果也可以有相同精确度的反氢原子光谱，那么比较这两者的光谱，可使稳定粒子现有的CPT界限大幅扩张。

Then the very last interview I had was with a small company called Spectra-Physics, which had an instrument division called Autolab.

Beck hopes to eventually use entire arrays of Josephson junctions to better measure quantum noise spectra in the terahertz region, noting that any anomaly there that cannot be explained by conventional physics could be a hint of dark energy.
