Ultrafast laser pulses reveal a material's hidden state of matter

What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it?

Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron Light Source II (NSLS-II)—a U.S.

Department of Energy (DOE) Office of Science user facility at DOE's Brookhaven National Laboratory—developed a methodology to generate "hidden" phases and understand why they work. ...
