Discover the First Visible and Manipulable Time Crystal

Discover the First Visible and Manipulable Time Crystal A small set of polystyrene balls floating in the air may not seem a significant finding. However, this system has allowed to observe a phenomenon that formerly belonged to the theoretical field: a classic time crystal that remains active without an external impulse. This experiment, developed by the University of New York, shows that these structures can be seen and manipulated with a portable device.

Now, we will explore in detail what is a time crystal and why it is relevant in the field of physics. A conventional crystal is defined by its ordered spatial structure, while a time glass is characterized by a periodicity in the time. This means that its movement is regularly repeated without the need of a constant external force. A classic time glass allows a dynamic system whose spatial-temporal symmetry is broken spontaneously. This concept implies that the system chooses its own rhythm, generating stable oscillations as emergent property. In the experiment, this oscillation adopts the form of a stable limit cycle that is maintained despite the friction and losses of energy. However, in this system, sound waves can transport moment away from particles, allowing non-reciprocal interactions. This means that one particle can influence another more without receiving the same force in return, creating unbalanced interactions. The polystyrene spheres, although passive on their own, acquire properties of active matter by interacting in the acoustic field. This active behavior arises from the relationship between particles, not from individual particles. If the configuration is changed, the movement disappears and the system returns to a passive state. Under certain conditions, the non-mutual interaction compensates the losses by friction, leading the system to a sustained oscillation regime. Two particles can access several dynamic states, including one that meets the definition of time crystal. This state is maintained for prolonged times, demonstrating its stability. One of the most striking aspects of the experiment is its macroscopic scale. Unlike other time crystals, this can be seen and sustained in the hand. The oscillations are recorded with a conventional camera, confirming that it is a robust and stable state. This opens the door to new applications in technology. The interest of the work goes beyond the physical framework, it can also suggest that it can be sustained.
