Researchers at Harvard University and the University of Maryland (UMD) have successfully generated time crystals based on the theoretical work of Princeton University scientists.
Princeton professor Shivaji Sondhi says the team at Harvard discovered the basic physics of how time crystals function, which builds on breakthroughs at Princeton focusing on understanding complex systems that are in and out of equilibrium.
The researchers believe their work could lead to concepts about how to safeguard information in quantum computers, which can be disrupted by interference by the outside world.
The crystals are formed from atoms and molecules configured across space and time, with periodic atomic movement.
Harvard's researchers realized non-equilibrium systems can be produced by periodically prodding a crystal by beaming a laser on its atoms. They created time crystals by generating an artificial lattice in a synthetic diamond, while the UMD team employed a chain of ytterbium ions.
