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 ...

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 ...

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 ...

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 ...

Aug. 13 (UPI) --For the first time, ultra-cold atoms have been used to detect changes in the surrounding environment in space, taking a step of revolutionizing how quantum science can be used. A new ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

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 ...

A new concept has been developed that has the potential to assist new instruments in the investigation of fundamental science topics such as gravitational waves and dark matter. A new concept has been ...

In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very ...

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 ...
