Assuming dark matter exists, its interactions with ordinary matter are so subtle that even the most sensitive instruments cannot detect them. In a new study, Northwestern University physicists now ...

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 ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible: gravitational waves or ripples in space-time caused by cataclysmic ...

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 ...

Jonathan Kwolek, Ph.D., a research physicist from the U.S. Naval Research Laboratory (NRL) Quantum Optics Section attaches fiber-optic cables to deliver light into the compact laser-delivery system, ...

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 ...
