Precision Measurements and Fundamental Physics I
- Jacinda Ginges
Masses of light nuclei provide a network of essential parameters used for the fundamental nature description. For example, the mass difference of tritium and helium-3 allows for an independent check of the limit on the electron-antineutrino mass.
The most precise mass measurements of the lightest nuclei, including helium-3, revealed considerable inconsistencies between the values reported by...
Phonons, quanta of Acoustic vibration, have much in common with photons, elementary excitation of Electro-Magnetic fields. Despite the fact that photonic devices have dominated physics and engineering for at least a century, and the acoustical systems have almost been forgotten. One of the main reasons for that is much lower energy losses exhibited by well designed photonic systems, e.g....
Over the past 20 years optical frequency combs [1], with atomic clocks [2], have been a powerful and enabling technology in the context of time and frequency measurement [1,2]. Impressively, optical atomic clocks have yielded an 8 order of magnitude improvement in accuracy in the past 30 years. These improvements are fueling a push toward redefinition of the SI second to optical atomic...
