A Michelson interferometer spectrometer carried aboard the Nimbus 3 satellite, launched 14 April 1969, measured the spectrum between 400 and 2000 wave numbers with a resolution of 5 wave numbers. High ...

Controlled magnetic gradients The atom chip used to create the magnet-based interferometer in the experiment. (Courtesy: Yair Margalit) An Israeli-led collaboration has used atom-chip technology to ...

Arvix paper contends the spacetime distortions resulting from the experimentally obtainable electric field of a parallel plate capacitor configuration cannot be detected by the White-Juday Warp Field ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely tuned laser experiment could, in principle, nudge gravitational waves ...

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.

The October 2014 Astronomy article, “Can the cosmos test quantum entanglement?” introduced an experiment my colleagues and I have proposed: using distant active galaxies called quasars to choose ...

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.

Quantum theory is strange. With it's particle-wave duality, and spooky action at a distance, it is a difficult theory to wrap your head around. But long before we were able to test some of its ...
