We present an updated review of Lorentz invariance tests in effective field theories (EFTs) in
the matter as well as in the gravity sector. After a general discussion of the role of Lorentz …

I review the current status of phenomenological programs inspired by quantum-spacetime
research. I stress in particular the significance of results establishing that certain data …

About 300 experiments have tried to determine the value of the Newtonian gravitational
constant, G, so far, but large discrepancies in the results have made it impossible to know its …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

Microgravity eases several constraints limiting experiments with ultracold and condensed
atoms on ground. It enables extended times of flight without suspension and eliminates the …

We evaluate the sensitivity of a dual cloud atom interferometer to the measurement of
vertical gravity gradient. We study the influence of most relevant experimental parameters on …

We report on a precision measurement of gravitational acceleration using ultracold strontium
atoms confined in an amplitude-modulated vertical optical lattice. An uncertainty Δ g/g≈ 10 …

Without using the relativity principle, we show how the Dirac equation in three space
dimensions emerges from the large-scale dynamics of the minimal nontrivial quantum …

We present the new mobile and robust gravimeter GAIN (Gravimetric Atom Interferometer),
which is based on interfering ensembles of laser cooled 87 Rb atoms in an atomic fountain …
