Aalto University physicists linked a time crystal to an external mechanical oscillator, turning a magnons-based time crystal in ultracold helium-3 into an optomechanical system. This first-of-its-kind coupling suggests new ways to build ultra-precise quantum sensors and improve quantum memory, bringing time-crystal physics closer to practical quantum technology as the system maintains coherent motion for minutes before decaying.
NYU physicists built a time crystal from a standing sound-wave field that levitates styrofoam beads and causes nonreciprocal interactions, effectively not following Newton’s third law. The one-foot-tall device is visible to the naked eye and uses acoustic levitation to propel bead motion, offering potential advances for quantum computing and understanding nonreciprocal processes in biology; the work was published in Physical Review Letters.
NYU physicists levitated tiny beads with sound to create a visible, classical time crystal whose nonreciprocal, uneven interactions between particles break Newton’s third law and drive self-sustained oscillations in a compact device; the simple setup could inform future quantum technologies and offer insights into biological timing systems, with the work published in Physical Review Letters.
NYU physicists have observed a visible, classical time crystal formed by millimeter beads levitated in a standing sound wave. The beads exchange sound waves in a nonreciprocal way, causing them to oscillate in a steady rhythm while hovering, a behavior that violates Newton's Third Law. The device stands about a foot tall and the work, published in Physical Review Letters, hints at links to biological timing systems and could influence future tech in quantum computing and data storage, though practical uses are still years away.
NYU researchers demonstrate a classical time crystal using an acoustic standing-wave field to levitate and couple tiny polystyrene beads; through non-reciprocal scattering of sound, the beads self-sustain a temporal oscillation without external driving, making it the simplest possible time-crystal system and offering a macroscopic platform to study non-reciprocity. The findings are reported in Physical Review Letters.
Physicists at the University of Colorado Boulder have created a visible time crystal using liquid crystals in a glass cell, which can be observed under a microscope or even by the naked eye under certain conditions. This development provides tangible proof of time crystals, which are structures that repeat motions over time and break traditional symmetry rules in physics. The new design exploits molecular kinks that behave like particles, and the researchers see potential practical applications such as anti-counterfeit measures and tiny data storage. This achievement marks a significant step in making quantum phenomena more accessible and understandable.

Physicists in Germany have created a time crystal made of indium gallium arsenide that lasted 40 minutes, a significant improvement over previous time crystals. The crystal, which breaks time-translation symmetry, was excited with polarized laser light, causing oscillations that made it "equivalent to a time crystal." While not perfect and exhibiting some melting, the team believes it could last even longer and potentially be used as a compact, highly flexible on-chip frequency standard.
Physicists at TU Dortmund University have successfully extended the lifespan of a time crystal, confirming a theoretical concept proposed by Nobel laureate Frank Wilczek. The time crystal, made of indium gallium arsenide, demonstrated periodic behavior in a system without periodic external influence, living millions of times longer than previously achieved. This breakthrough in quantum physics marks a significant advancement and opens up possibilities for further research and analysis of chaotic behavior in such systems.
Researchers from TU Dortmund University have created a semiconductor from indium gallium arsenide that exhibits continuous time crystal behavior, setting a new record for sustained oscillations lasting at least 40 minutes. This breakthrough in quantum physics opens the door to new possibilities in precise frequency measurement and could lead to the development of new kinds of hardware.
Physicists from TU Dortmund University have successfully created a highly durable time crystal, a phenomenon postulated by Nobel laureate Frank Wilczek around ten years ago. This time crystal, made of indium gallium arsenide, demonstrated a periodic behavior in time, with a lifetime of at least 40 minutes, which is 10 million times longer than previously demonstrated. The crystal's nuclear spin polarization spontaneously generates oscillations, equivalent to a time crystal, and can potentially live even longer. This breakthrough opens up possibilities for studying chaotic behavior in such systems and has been published in Nature Physics.
In a locked-room mystery, a detective investigates the death of a scientist in a windowless lab. The victim's body is missing facial features, but the detective finds a notepad with drawings and equations related to a time crystal. As the investigation unfolds, the detective discovers that the killer is his own junior detective, who reveals himself as a spy protecting the time crystal. A deadly confrontation ensues, resulting in the detective's demise. The story explores the unsettling implications of a steady-state equilibrium of life and death.
Researchers at the University of Southampton have demonstrated a continuous time crystal state using a photonic metamaterial. The system used is a 2D array of plasmonic metamolecules supported by flexible nanowires. Continuously illuminating this photonic metamaterial with a light that resonates with the plasmonic mode of the metamolecules caused a spontaneous phase transition to a state that possesses the key properties of a continuous time crystal. This state is characterized by continuous oscillations resulting from many-body interactions between the metamolecules. The unique system realized by the researchers could open new avenues for research into time crystals and dynamic classical many-body states in the strongly correlated regime.
Physicists at Imperial College London have recreated the double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics. The team used a metamaterial that changes its reflectance in femtoseconds to create "slits" for light. The researchers want to explore the phenomenon in a "time crystal," which is analogous to an atomic crystal, but where the optical properties vary in time.
