Researchers create 'beautiful marriage' of quantum enemies

Using nitride-based materials, researchers created a material structure that simultaneously exhibits superconductivity - in which electrical resistance vanishes completely - and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.

The future of electronics is stretchy (w/video)

Researchers have developed a material and fabrication process that can rapidly make these devices stretchier, more durable, and closer to being ready for mass manufacturing.

New phenomena for the design of future quantum devices

For the first time, Kohn anomaly has been theoretically predicted in a topological material and experimentally observed in a Weyl semimetal. This research revealed how the topological electronic states can alter the phonon spectra in materials, which hold promise for future quantum applications.

Scientists find way for mass production of near-zigzag carbon nanotubes

Researchers report a method for submilligram-scale preparation of multiple single-chirality near-zigzag carbon nanotubes such as (9, 1), (9, 2), (10, 2) and (11, 1) nanotubes. This new technique breaks through the bottleneck of mass production of single-chirality near-zigzag single-wall carbon nanotubes, and provides a material basis for the disclosure of their properties and applications.

A speed limit also applies in the quantum world

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists have now shown what the speed limit is for complex quantum operations.
