There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is ...

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

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

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

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

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 ...

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 ...

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

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

A new experiment captures a single parcel of light morphing between wave and particle. Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon ...

IBM’s Scanning Tunneling Microscope, or STM for short, uses an atomically sharp needle that passes over the surface of an (electrically conductive) object – the distance between the tip and object ...

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