Description
The measurements of the Earth 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 they provide 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 part in 10^9 of the Earth rotation rate. The GINGER project is based on an array of ring lasers, and will be installed inside the Gran Sasso laboratory, the plan is to have GINGER operative in 3 years time.
