Time-periodic forcing in the form of coherent radiation is a standard tool for the coherent
manipulation of small quantum systems like single atoms. In the last years, periodic driving …

This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

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 …

Atom interferometers are powerful tools for both measurements in fundamental physics and
inertial sensing applications. Their performance, however, has been limited by the available …

We discuss effects of loss of coherence in low energy quantum systems caused by or related
to gravitation, referred to as gravitational decoherence. These effects, resulting from random …

We review the field of atom interferometer inertial sensors. We begin by reviewing the path
integral formulation of atom interferometers and then specialize the treatment to light-pulse …

We report on a conceptually new test of the equivalence principle performed by measuring
the acceleration in Earth's gravity field of two isotopes of strontium atoms, namely, the …

We report on the realization of a matter-wave interferometer based on single-photon
interaction on the ultranarrow optical clock transition of strontium atoms. We experimentally …

General Relativity is today the best theory of gravity addressing a wide range of phenomena.
Our understanding of physical laws, from cosmology to local scales, cannot be properly …
