Scientists Make "Time Crystals"... in Liquid Crystals!

Researchers created continuous space-time crystals (CSTCs) in a nematic liquid crystal using constant, ambient-power light. These CSTCs, made of topological solitons, spontaneously break time-translation symmetry and are robust against perturbations, meeting criteria for time crystal classification.

Possible Conflicts of Interest

The authors have a patent application related to CSTCs submitted by the University of Colorado concurrently with this paper (US patent application no. 63/764,363).

Identified Weaknesses

Generalizability to Other Systems

The study focuses on a specific liquid crystal system. It's unclear whether similar time crystal behavior can be observed in other materials or systems. Further research is needed to determine the broader applicability of these findings.

Long-Term Stability

While the CSTCs persist for hours, the paper notes that the temporal periodicity can drift by ~10% over an hour. This raises questions about the long-term stability of these time crystals and their practical utility.

Technological Applications

The suggested technological applications, like anti-counterfeiting and telecommunications, are highly speculative at this stage. Significant further development is needed to assess their feasibility and practicality.

Rating Explanation

This study presents a novel observation of continuous space-time crystals in a classical system. The experimental and theoretical work are well-integrated, and the findings meet established criteria for time crystal classification. While questions remain about generalizability and long-term stability, the work is a valuable contribution to the field. The disclosed conflict of interest related to the patent application has been taken into account when assessing the rating.
