MIT precisely separates the atoms of bose einstein condensate for more precise...

Atom interferometry is the most sensitive known technique for measuring gravitational forces and inertial forces such as acceleration and rotation. It's a mainstay of scientific research and is being commercialized as a means of location-tracking in environments where GPS is unavailable. It's also extremely sensitive to electric fields and has been used to make minute measurements of elements' fundamental electrical properties.

The most sensitive atom interferometers use exotic states of matter called Bose-Einstein condensates. In the latest issue of Physical Review Letters, MIT researchers present a way to make atom interferometry with Bose-Einstein condensates even more precise, by eliminating a source of error endemic to earlier designs.

Interferometers using the new design could help resolve some fundamental questions in physics, such as the nature of the intermediate states between the quantum description of matter, which prevails at very small scales, and the Newtonian description that everyday engineering depends on.
