Atom interferometer - Wikipedia
An atom interferometer uses the wave-like nature of atoms in order to produce interference. In atom interferometers, the roles of matter and light are reversed compared to the laser based interferometers, i.e. the beam splitter and mirrors are lasers while the source emits matter waves (the atoms) rather than light.
Atom interferometry Introduction - Müller Group
Atom interferometry is the technique that underlies most of our precision measurements. We exploit the fact that matter, like light, exhibits wave-like properties. Atoms, unlike light, are massive and bear gravitational signals in their interference patterns. To understand atom interferometry, we first must understand optical interferometry.

Gravity surveys using a mobile atom interferometer - Science
2019年9月6日 · We have developed a mobile atomic gravimeter and performed tidal gravity measurements and gravity surveys. Our instrument uses a novel pyramidal MOT that takes advantage of single-beam atom interferometry and offers differential pumping, simple laser-to-gravity alignment, and enhanced vibration isolation.

2020年1月29日 · We provide an introduction into the field of atom optics and review our work on interferometry with cold atoms, and in particular with Bose-Einstein condensates. Here we emphasize applications of atom interferometry with sources of this kind. We discuss tests of the equivalence principle, a quantum tiltmeter, and a gravimeter.
