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 ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

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 ...

The ZEUS laser facility at the University of Michigan has roughly doubled the peak power of any other laser in the U.S. with its first official experiment at 2 petawatts (2 quadrillion watts). At more ...
