“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

One of the most famous experiments in quantum physics, which first showed how particles can bizarrely behave like waves, has now been carried out on the largest molecules ever. Researchers have sent ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...

Scientists observe unusual interference phenomena by scattering laser light from two atoms trapped inside an optical resonator. MPQ scientists observe unusual interference phenomena by scattering ...

Molecular paths: The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the ...
