A Strange New Time Crystal Emerges From Synchronized Vibrations
Physicists have discovered a new way for time crystals to form through a process called 'wave coarsening,' where competing vibrations spontaneously synchronize. This research demonstrates how stable, repeating patterns in time can emerge from chaos in two-dimensional metamaterials.
Why it matters
Understanding how time crystals form helps researchers overcome the fragility of these systems, potentially leading to advancements in quantum computing and material science.
To us mortals, the flow of time goes one way.
Yesterday is gone, tomorrow is yet to come, and no matter how precisely and faithfully a clock marks the passing seconds, we can never return to a moment that has passed.
But for a time crystal , things are very different.
The constituent ranks of this mysterious state of matter – be they atoms, sound waves, or topological defects – are strictly regimented in time, a repeating pattern of beats that could be snipped from a recording at regular intervals and perfectly superimposed, one over another.
Once thought impossible, time crystals have been observed in systems from physical atomic lattices to levitating styrofoam.
