‘Time crystal’ created in lab

Flipped ions return to original positions periodically to demonstrate new form of symmetry breaking

TIME CRYSTAL  Crystals can form in time as well as in space, scientists have confirmed. Scientists hit a chain of ions with lasers to create the time crystal, which undergoes symmetry breaking in time, just as a normal crystal (shown above) breaks the symmetry of space.

It may sound like science fiction, but it’s not: Scientists have created the first time crystal, using a chain of ions. Just as a standard crystal repeats in a regular spatial pattern, a time crystal repeats in time, returning to a similar configuration at regular intervals.

“This is a remarkable experiment,” says physicist Chetan Nayak of Microsoft Station Q at the University of California, Santa Barbara. “There is a ‘wow factor.’”
