Building an understanding of quantum turbulence from the ground up

Most people only encounter turbulence as an unpleasant feature of air travel, but it's also a notoriously complex problem for physicists and engineers. The same forces that rattle planes are swirling in a glass of water and ...

Scientists demonstrate time reflection of electromagnetic waves

When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored surface, creating the common phenomenon called spatial ...

Magnetism fosters unusual electronic order in quantum material

Âé¶¹ÒùÔºicists were surprised by the 2022 discovery that electrons in magnetic iron-germanium crystals could spontaneously and collectively organize their charges into a pattern featuring a standing wave. Magnetism also arises ...

Ringing an electronic wave: Elusive massive phason observed in a charge density wave

Researchers at the University of Illinois Urbana-Champaign have detected the existence of a charge density wave of electrons that acquires mass as it interacts with the background lattice ions of the material over long distances.

Observing phononic skyrmions based on the hybrid spin of elastic waves

Skyrmions are extremely small with diameters in the nanoscale, and they behave as particles suited for information storage and logic technologies. In 1961, Tony Skyrme formulated a manifestation of the first topological defect ...

Making engineered cells dance to ultrasound

Let's say you needed to move an individual cell from one place to another. How would you do it? Maybe some special tweezers? A really tiny shovel?

Designing advanced 'BTS' materials for temperature and long-wave infrared sensing

Materials scientists are often inspired by nature and therefore use biological compounds as cues to design advanced materials. It is possible to mimic the molecular structure and functional motifs in artificial materials ...

Researchers detail never-before-seen properties in a family of superconducting Kagome metals

Dramatic advances in quantum computing, smartphones that only need to be charged once a month, trains that levitate and move at superfast speeds. Technological leaps like these could revolutionize society, but they remain ...
