Unmasking the magic of superconductivity in twisted graphene

The discovery in 2018 of superconductivity in two single-atom-thick layers of graphene stacked at a precise angle of 1.1 degrees (called 'magic'-angle twisted bilayer graphene) came as a big surprise to the scientific community. ...

Phase transiting to a new quantum universe

(Phys.org) —Recent insight and discovery of a new class of quantum transition opens the way for a whole new subfield of materials physics and quantum technologies.

Magnetism Governs Properties of Iron-Based Superconductors

(PhysOrg.com) -- Though a year has passed since the discovery of a new family of high-temperature superconductors, a viable explanation for the iron-based materials’ unusual talent remains elusive. But a team of scientists ...

Quantum fluctuations sustain the record superconductor

Calculations performed by an international team of researchers from Spain, Italy, France, Germany, and Japan show that the crystal structure of the record superconducting LaH10 compound is stabilized by atomic quantum fluctuations. ...

'Flawed' material resolves superconductor conundrum

Christopher Parzyck had done everything right. Parzyck, a postdoctoral researcher, had brought his nickelate samples—a newly discovered family of superconductors—to a synchrotron beamline for X-ray scattering experiments. ...
