Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those ...

Researchers in Drexel University's College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

Columbia University researchers report the first observation of electron waves trapped in place inside a two-dimensional ...

A theory inspired by whale tracking suggests that interference could make the peak of a light-wave packet appear to travel faster than light—without transmitting information superluminally. Whales are ...

Interference in plane-wave combinations of water waves is predicted to give rise to structures that are usually found in optical, elastic, and quantum systems. Figure 1: Water surface waves can form ...

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 ...
