A group of scientists created "slits" in time, allowing them to send light through the slits in a twist on an experiment first run over 200 years ago. In the original experiment, scientists sent light ...

Some of the heaviest atoms in the universe barely exist long enough to be ...

Scientists have long known that light can sometimes appear to exit a material before entering it -- an effect dismissed as an illusion caused by how waves are distorted by matter. Now, researchers at ...

In a first, scientists have shown that they can send light through “slits in time” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a ...

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser ...

A beam of electrons crossed just a few millimeters of plasma, then helped trigger an effect that usually belongs to massive ...

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that’s what happened in UMD’s Energy Research Facility, an unremarkable ...

Researchers set a record by guiding light in 45-meter-long air wave-guides. It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But ...
