Sound-Wave Time Crystal Goes Visible, Challenges Newton’s Third Law

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.

Cavity Magnonics Enables Nonreciprocal Light Speed Control

Researchers have demonstrated a novel cavity magnonics device that nonreciprocally controls the speed of light, allowing microwave pulses to travel at different speeds depending on direction, which could impact advanced communication and quantum technologies.

"Enhancing Water Filtration Efficiency with Anti-Gravity Material Channels"

Scientists have developed a composite material, consisting of a hydrogel with embedded nanofillers, that can channel mechanical energy in a preferred direction. This material acts in a "nonreciprocal" way, allowing for the utilization of wasted vibrational energy. The researchers demonstrated that the material could make liquid droplets rise within it using vibrational movements. This breakthrough could have potential applications in various fields, such as electricity, photonics, magnetism, and sound, where channeling mechanical energy is challenging.
