For example, when a magnetic field is applied perpendicularly ... the anomalous metallic state is a broadened quantum critical ground state for the superconductor-insulator transition.

a type of superconductor that is more resistant to magnetic fields than conventional superconductors ... the paper’s authors ...

Here, the authors report the observation of a SDE under zero magnetic field up to 72 K in a high-transition-temperature cuprate superconductor.

Researchers used cutting-edge X-ray techniques to gain new insights into 'infinite-layer' nickelate materials.
