Researchers propose a new design principle for nonlocal metamaterials that precisely control vibrations and waves, enabling precise control over wave propagation and motion. The proposed technology is expected to serve as a foundational platform for next-generation vibration control and high-performance sensing technologies.

Scientists have designed metamaterials that can produce rotons, quasiparticles that behave like free particles, without using quantum effects under normal conditions. These materials could enable the manipulation of sound waves in ways previously impossible, such as bouncing or redirecting them.

Researchers at the University of Chicago have successfully created a roton structure in an atomic superfluid of cesium-133 using the shaken lattice technique. This breakthrough enables experimentation on long-cloaked mysteries of the roton, potentially paving the way for increased robustness in superconductors.

The Rotary Rocket Company is set to conduct atmospheric tests for its revolutionary heli-rocket Roton. The craft will use four 7-meter-long helicopter blades to slow its descent and potentially slash the cost of getting satellites into space. If successful, the first Roton could blast into orbit as early as next year.
