We describe a dual-axis atomic spin gyroscope based on an alkali metal-noble gas
comagnetometer. Alkali metal vapor is optically pumped, and then the noble gas is …

Many phenomena and fundamental predictions, ranging from Hawking radiation to the early
evolution of the Universe rely on the interplay between quantum mechanics and gravity or …

Gyroscopes IN GEneral Relativity (GINGER) is a proposed experiment with the aim of
measuring in a ground laboratory the gravitoelectric and gravitomagnetic effects foreseen by …

The debate on gravity theories to extend or modify general relativity is very active today
because of the issues related to ultraviolet and infrared behavior of Einstein's theory. In the …

The impact of light scalars coupled conformally and disformally to matter on the geodetic
and frame-dragging precessions is calculated. For larger frequencies the disformal …

We performed continuous recordings (May 2015–January 2017) of hydraulic pressure and
electrical conductivity of groundwater in the 190 m-long horizontal S13 borehole drilled next …

Measuring in a single location on Earth its angular rotation rate with respect to the celestial
frame, with a sensitivity enabling access to the tiny Lense-Thirring effect, is an extremely …

Mechanical rotation plays a central role in fundamental physics theories and has profound
connections with the theory of general relativity. However, very few experiments have so far …

The sensitivity to angular rotation of the top class Sagnac gyroscope GINGERINO is carefully
investigated with standard statistical means, using 103 days of continuous operation and the …

Inertial sensors are important at application level and also in fundamental physics. Ring
laser gyroscopes, which measure angular rotation rates, are among the most sensitive ones …
