In a preprint posted online Thursday nightGoogle researchers in collaboration with physicists at Stanford, Princeton and other universities say they have used Google’s quantum computer to demonstrate a genuine “time crystal.” Also, a separate research group claimed earlier this month have created a time crystal in a diamond.
A novel phase of matter that physicists have struggled to realize for many years, a time crystal is an object whose parts move in a regular and repetitive cycle, keeping this change constant without burning energy.
“The consequence is amazing: you evade the second law of thermodynamics,” he said. Roderich moessner, director of the Max Planck Institute for Complex Systems Physics in Dresden, Germany, and co-author of the Google paper. That is the law that says that disorder always increases.
Time crystals are also the first objects to spontaneously break the “translational symmetry of time,” the common rule that a stable object will remain the same over time. A time crystal is stable and constantly changing, with special moments occurring at periodic intervals in time.
The crystal of time is a new category of phases of matter, expanding the definition of which phase …
