The Earth's rotation rate variations, certainly important for Earth science, are relevant also for fundamental physics investigation, as they contain general relativity terms, such as de Sitter and Lense Thirring, and unique data to investigate Lorentz violations. Long term continuous operation and very high sensitivity are required, the limit to be reached to study fundamental physics is 1...
A multitude of different globally distributed and independent mass transport phenomena lead to non-predictacle fluctuations in the Earth's rotation rate $\Omega_{e}$. Large Sagnac interferometers in the form of ring lasers enable the instantaneous observation of variations in $\Omega_{e}$ at a level of a few ppb. Here, the benefit of this technique, as well as recent advancements and future...
In this talk we briefly review the gravitoelectromagnetic analogies that arise in General Relativity: they are powerful tools to explain peculiar general relativistic effects in terns of known results of classical electromagnetism. In particular, we focus on the perspective of measuring these effects on the Earth and in the Solar System, with emphasis on the detection of the magnetic-like...
