Researchers discovered that when atoms interact and remain entangled with light, they emit stronger, more coordinated bursts ...

An experiment 180 years ago first demonstrated a connection between light and electromagnetism – but the link is deeper than ...

Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the ...

For nearly two centuries, physics textbooks have treated light as magnetically indifferent to the materials it passes through ...

Slowing down light is not as easy as it sounds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The phenomenon of light slowing down as it passes ...

I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser’s group had a project dedicated to studying chemical reactions with attosecond pulses. Before ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

The 2023 Nobel Prize in physics has been awarded to three scientists who created pulses of light so short they can be used to watch the inner workings of atoms. Pierre Agostini, Ferenc Krausz, and ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

An international team of physicists has cooked up with a new theory that could allow for objects to travel faster than the speed of light — and while they say it wouldn’t technically violate the laws ...
