- Scientists have discovered a new phase of matter called a time rondeau crystal (TRC).
- Unlike solids or liquids, TRCs show order in time rather than in space.
- Time crystals exhibit perfect periodic motion, while TRCs combine long-term order with short-term randomness.
- The TRC was created using carbon-13 nuclei spins in diamond, controlled by microwave pulses with structured randomness.
- This new phase lasts several seconds and fades as the system heats up, showing metastability.
