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

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

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

The particle-wave nature of light has fascinated researchers for more than 200 years, but a new experiment has allowed researchers to visualize it like never before. This image was taken by turning an ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...

Researchers from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

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