A time crystal made of giant atoms - EurekAlert


A crystal is an arrangement of atoms that repeats itself in space, in regular intervals. Nobel Prize winner Frank Wilczek raised the question: Could there also be a time crystal – an object that repeats itself not in space but in time? For years, this idea has caused much controversy.
