For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...

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

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...
