NYU Researchers Discover New Type of Time Crystal Defying Newton's Third Law

Researchers at New York University (NYU) have unveiled a new type of time crystal that levitates on a cushion of sound, challenging Isaac Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. This discovery, detailed in a recent paper published in *Physical Review Letters*, involves styrofoam-like beads suspended in mid-air between two arrays of speakers, creating a unique quantum system where particles interact nonreciprocally.

The time crystals consist of beads of expanded polystyrene, which are levitated using standing sound waves. As these beads float, they exchange sound waves, leading to unbalanced interactions. According to Mia Morrell, a graduate student at NYU and lead author of the study, larger particles scatter more sound than smaller ones, resulting in differential influences akin to two ferries creating waves of varying strengths as they approach a dock. This mechanism allows the beads to move in periodic patterns, mimicking the behavior of time crystals.

The researchers believe that this new form of time crystal could have significant academic and practical implications. David Grier, a senior author of the study, remarked that the simplicity of the system might serve as a foundational model for understanding more complex phenomena, such as biological rhythms and financial market trends. The nonreciprocal interactions observed in the time crystals may parallel biochemical networks in the human body, which also exhibit similar behaviors.

The NYU team emphasized the potential of their discovery to expand the understanding of time crystals and their applications. Grier stated, “This was a discovery in the truest sense,” highlighting the rich behaviors emerging from a simple system. Morrell added, “The key point is that time crystals select their own frequency without being told what to do by any external force,” underscoring the unique characteristics of this new time crystal.

While the findings are groundbreaking, some experts caution against overestimating the immediate practical applications of time crystals. Critics argue that while the theoretical implications are intriguing, the transition from laboratory discoveries to real-world applications remains a significant challenge.
