Since the first proof-of-principle experiments over 25 years ago, atom interferometry has
matured to a versatile tool that can be used in fundamental research in particle physics …

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 …

Gravimetry is a well-established technique for the determination of sub-surface mass
distribution needed in several fields of geoscience, and various types of gravimeters have …

Mobile gravimetry is important in metrology, navigation, geodesy, and geophysics. Atomic
gravimeters could be among the most accurate mobile gravimeters but are currently …

The research on cold-atom interferometers gathers a large community of about 50 groups
worldwide both in the academic and now in the industrial sectors. The interest in this sub …

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 …

Chip-scale atomic devices combine elements of precision atomic spectroscopy, silicon
micromachining, and advanced diode laser technology to create compact, low-power, and …

The accelerated expansion of the universe motivates a wide class of scalar field theories
that modify general relativity (GR) on large scales. Such theories require a screening …

We discuss the basic physics and instrumentation issues related to high-performance
physical and inertial sensors based on atomic spectroscopy. Recent work on atomic …

Limits on the long-term stability and accuracy of a second generation cold atom gravimeter
are investigated. We demonstrate a measurement protocol based on four interleaved …
