Researchers Find ‘time Liquids’ Lacking Perfect Temporal Order

Quantum ZeitgeistOctober 25, 20264 min read

Spins are now exhibiting periodic behaviour lasting far beyond the driving signal’s initial pulse, a feat previously thought impossible without perfectly timed external forces. This discovery reveals an alternative to established “time crystals”, demonstrating stable order even when driven by noise rather than precise coherence. The resulting ‘discrete time liquids’ suggest temporal structures may persist within systems once considered too chaotic for such organisation.

The challenge of creating stable temporal order from noisy signals has prompted investigation into new states of matter by researchers affiliated with the Max Planck Institute for the Physics of Complex Systems and South China Normal University, Guangdong Provincial Key Laboratory of Quantum Engineering and Quantum Materials. They identified “discrete time liquids”, a novel form of spatiotemporal organisation arising within two-dimensional spin systems driven by fluctuating energy from a cavity. This discovery enables prediction of…
