Ultrafast lasers tracked plasma formation and ionization in copper with picosecond precision. Results show rapid ion growth ...
A new study by researchers at the Massachusetts Institute of Technology (MIT) now bridges ...
Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...
Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive ...
In 1927, Albert Einstein and Neils Bohr debated the nature of what’s known as complementarity—the idea that a photon’s dual wave-like and particle natures can’t be measured at the same time. Now, two ...
Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave or a particle. Columnist Karmela Padavic-Callaghan finds that the matter ha ...
When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely ...
About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with ...
