Many efforts are devoted to probe theories of gravity by Earth and space-based experiments at ultraviolet and infrared scales. In this debate, we propose straightforward tests by the GINGER experiment, which, being Earth based, requires little modeling of external perturbations, allowing a thorough analysis of the systematics, crucial for experiments where sensitivity breakthrough is...
We discuss here the possibility to detect high frequency gravitational waves by exploiting gravitomagnetic effects. In the laboratory frame, using the construction of the Fermi frame, the field of a gravitational wave can be described in terms of gravito-electromagnetic fields that are transverse to the propagation direction and orthogonal to each other. In particular, the gravito-magnetic...
Atomic Clock Ensemble in Space (ACES) is developing a cold-atom clock and high-performance links to test general relativity from the International Space Station. With a fractional frequency instability and inaccuracy of 1x10^{-16}, the ACES clock signal will establishing a worldwide network to compare clocks in space and on ground. ACES will provide an absolute measurement of Einstein's...
ZAIGA is an acronym for Zhaoshan long-baseline Atom Interferometer Gravitation Antenna. ZAIGA project concept was proposed in 2019. The first phase of the project was funded recently. It will be a platform to test gravity theory with large scale atomic interferometers, atomic gyros and atomic optical clocks. In this talk I will tell the progress in design and building of the project.
Since the first detection of gravitational waves in 2015, Advanced Virgo and Advanced LIGO interferometers have been able to detect almost 100 sources, starting the multi-messenger astronomy era. We will provide an overview of Advanced Virgo+ detector, concentrating on the seismic isolation system of its main optical components, the so-called superattenuator. We will discuss its mechanics and...
This presentation will review the implications of Lorentz Violation for Sagnac gyroscopes using the framework of the Standard-Model Extension.
From atom interferometry to NMR, table-top experiments have been pushing the frontier of precision for decades. In this talk, I will present a particle theory perspective on how these advances can be used to look for well-motivated beyond the standard model particles and phenomena.
