Finding out what the universe is actually made of remains one of the ultimate ...

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 ...

INTERFEROMETERS for the testing and corretion of prisms and of lenses (for axial pencils) have been described in the Philosophical Magazine (vol. xxxv., January, 1918, p. 49). In its simplest form the ...

A prototype quantum sensor developed by researchers at Imperial has demonstrated for the first time that a key principle ...

A team of researchers from the University of Glasgow and the University of Southampton has devised a novel way to test quantum mechanics in a non-inertial reference frame by using a rotating ...

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 ...

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 ...

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 ...

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 ...

This includes proposals such as the Atom Interferometry CERN Experiment (AICE), which would apply similar techniques over ...
