A closer look at “Physicists Discover a New Type of Time Crystal from Coupled Vibrations”, exactly as the source publishes it. A team of physicists has identified a new kind of time crystal, a phase of matter that repeats in time rather than space, by observing synchronized vibrations in a system of coupled resonators. The research, reported by ScienceAlert, describes how the researchers induced a time-crystalline state using a classical system, not a quantum one, which could make time crystals easier to study and potentially use in future technologies. The discovery hinges on a phenomenon called 'exceptional points' where two vibrational modes coalesce.
By carefully tuning the coupling and loss rates, the scientists created conditions where the system spontaneously broke time-translation symmetry, leading to periodic motion that is robust against perturbations. This new time crystal is 'strange' because it emerges from a non-Hermitian system, meaning it exchanges energy with its environment, unlike isolated quantum systems previously studied.
