Rotons

Novel materials: Sound waves traveling backwards

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.

Roton quasiparticles observed in quantum gas

Researchers at the University of Innsbruck have successfully detected roton excitations in a dipolar quantum gas for the first time. The discovery paves the way for further research into superfluidity and supersolid states, which exhibit both solid-like and fluid-like properties.

Cesium atoms shaken, not stirred, to create elusive excitation in superfluid

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.

It's A Countdown For Roton, The Revolutionary Heli-Rocket

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.
