Extremely precise measurements are possible using atom interferometers that employ the wave character of atoms for this purpose. They can thus be used, for example, to measure the gravitational field ...

Atom interferometry has emerged as a transformative approach in both fundamental physics and practical applications, utilising the wave nature of atoms to measure minute effects of gravity, rotation ...

The figure shows how atoms with opposing spins are separated into two streams using magnets and then brought back together, creating an interference pattern. If any external quantum processes affect ...

Sandia National Laboratories scientist Jongmin Lee, left, prepares a rubidium cold-atom cell for an atom interferometry experiment while scientists Ashok Kodigala, right, and Michael Gehl initialize ...

Toward the development of a “quantum compass” for navigation when GPS signal unavailable. Sandia scientists prepare a rubidium cold-atom cell for an interferometry experiment. Scientists are ...

NASA’s Cold Atom Lab, shown where it’s installed aboard the International Space Station, recently demonstrated the use of a tool called an atom interferometer that can precisely measure gravity and ...

A team of UC Berkeley researchers, led by campus physics professor Holger Müller, has made progress in the field of dark energy, developing a new method in atom interferometry that has implications ...

Dark energy — a mysterious force pushing the universe apart at an ever-increasing rate — was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle ...

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...
