CANISIUS is the official name of the new spin-echo neutron interferometer developed at Atominstitut, TU Wien. It enables ...

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using ...

Physicists 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 of atoms.

Using an atom interferometer, scientists have tested one of the foundations of Einstein's general theory of relativity: that time slows down in a gravitational field. Their experiment proves that ...

A lot of what I write is about measurement, not because I’m in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

Who’s who: The quantum Alice in Wonderland would like to understand whether the many “Twindeldum-Twindeldees” she sees are really identical or not, and uses the new interferometer for this purpose.

Gravimetry, or the measurement of the strength of a gravitational field (or gravitational acceleration), has been of great interest to physicists since the 1600s. One of the most precise ways to ...

An interferometer sounds like something complicated, and in a way, it is. But it is also pretty easy to build one with some common materials. [Let’s Innovate] has instructions for how to make an ...
