This floating time crystal breaks Newton’s third law of motion
- Researchers at New York University created a nonreciprocal time crystal using sound waves to levitate beads in mid-air.
- The beads exchange sound waves in a way that appears to break Newton’s Third Law, producing a nonreciprocal interaction.
- The device is compact, about one foot tall, and the effect is visible to the naked eye.
- The study, published in Physical Review Letters, links the time crystal to potential advances in quantum computing and data storage.
- The research may help illuminate biological timing systems, such as circadian rhythms.
- The beads used are small styrofoam beads moved by standing sound waves in an acoustic levitator.
- Larger beads produce stronger forces, creating imbalanced interactions that drive the system’s rhythm.
- The work was supported by National Science Foundation grants DMR-21043837 and DMR-2428983.
- The scientists describe the system as simple yet revealing complex physics with broad implications.
- The findings appear in Physical Review Letters and may influence future quantum technologies and data storage solutions.
