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 ...

The current state of the art of embedded motion sensing is based around micro-electromechanical systems (MEMS) devices. These miracles of microfabrication use tiny silicon structures, configured to ...

Atom interferometers usually control matter waves and particularly particle velocity using lasers. Thus, the growth of atom interferometer application has been strongly tied to the development of ...

An atom interferometer embedded in an optical cavity requires less power compared to previous techniques and may work with a wider variety of atoms and molecules. Atom interferometry, in which atomic ...

On the morning of August 31, 2026, roughly 25 physicists filed into CERN's Theory Conference Room — a compact, whiteboard-lined space inside Building 4 on the Geneva campus — and began what the ...

As the weakest fundamental force, gravity yields only small accelerations from millimetre-scale masses, making them difficult to detect. Detecting the gravitational ...

Almost a hundred years ago, physicists theorized out what free fall should do to a quantum wave. If the solution they came up with is wrong, quantum mechanics and Einstein’s theory of gravity flatly ...

Figure 1: The basic elements of point source interferometry are depicted here. (a) The method starts with a small cloud of ultracold atoms (blue), which is launched upward inside an evacuated ...

A method that increases the precision of atom interferometers could lead to improved force and energy measurements for testing physics beyond the standard model. An atom interferometer measures very ...

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 ...
