"Going Deep" to measure Earth’s rotational effects

The recent development of a Sagnac gyrolaser installed at the INFN Gran Sasso National Laboratory paves the way to realise multi-axial systems with enough experimental precision to reveal measurable effects of Einstein’s general theory of relativity. The fingerprint of these effects, namely Lense-Thirring and de Sitter effect, appears as a tiny disturbance on the Erath rotation. The GINGER (Gyroscopes in General Relativity) experiment involves Alberto Porzio from CNR-SPIN together with an international team lead by Angela Di Virgilio from INFN Pisa. Recent results on the sensitivity reached, so far, by the GINGERino prototype highlighted by AIP here have been published in:
Review Scientific Instruments 88, 034502 (2017); doi: 10.1063/1.4977051.
