What is the discovery

Scientists report a new phase of matter called the intramolecular crystal (IMC). Unlike ordinary solids (ordered in space) or liquids (disordered), the IMC shows a mixed pattern in time: long-term regularity and randomness coexist. Experiments controlling spins of carbon-13 nuclei in diamond with microwave pulses revealed a predictable yet aperiodic time pattern. This state was long-lived (metastable) and robust to small disturbances.

Why it matters

• Expands phase taxonomy: time can host quasi-orders just as space does.
• New tools for physics: helps probe hidden order inside apparent disorder.
• Potential applications: ultra-selective quantum sensors and improved quantum information devices.

Key terms

• Intramolecular crystal (IMC): time-ordered state where regularity and randomness coexist
• Aperiodic / quasi-periodic: ordered pattern without a fixed repeating period
• Spin: quantum angular momentum of particles, used as controllable bits
• Metastable: long-lasting but not permanent state

One-line wrap

IMC shows that time itself can hide order inside disorder, opening fresh paths for precision sensing and quantum control.
