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 ...

The new INTERFEROMETER VI-direct SLP represents a cost effective phase shifting interferometer. Equipped with a high resolution camera, phase shifting unit and stabilized HeNe laser, the ...

Nanopositioning specialist Queensgate and the UK’s National Physical Laboratory (NPL) have forged a productive collaboration yielding a good-practice implementation model for Queensgate’s in-house ...

An experiment by a team of researchers led from the University of Waterloo's Institute for Quantum Computing shows, for the first time, that a wave property of neutrons, Orbital Angular Momentum, can ...

The Einstein equivalence principle (EEP) has a central role in the understanding of gravity and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies equivalence ...

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 ...

Grating-coupled interferometry (GCI) is a surface based, a label-free optical sensing technique used for real-time binding kinetic measurements. 1 Typically, GCI is used to detect binding events ...

Space Warp equations are being tested using an instrument called the White-Juday Warp Field Interferometer. At Johnson Space Center, Eagleworks has initiated an interferometer test bed that will try ...

Physicists in Germany have used an atomic interferometer to perform the most accurate ever test of the equivalence principle at the level of atoms. Sebastian Fray and colleagues at the Max Planck ...
