For three decades, one quiet crystal has sat at the center of a fierce argument about how exotic superconductors really work.

With pulses of sound through tiny speakers, Cornell physics researchers have clarified the basic nature of a new superconductor. Since it was found to be a superconductor about five years ago, uranium ...

Researchers have devised a new technique to create and control a class of high-temperature superconductors, offering potential for unprecedented forms of superconductivity. The method involves precise ...

Experiments show Josephson junction-like behavior can arise with only one superconductor, challenging the standard two-superconductor model.

Researchers just witnessed a superconductor behavior that defies our current understanding of physics. At a certain electron density, quantum fluctuations—the phenomena that make superconductors stop ...

Chinese researchers are making variations of LK99 room temperature superconductor materials with more sulfur and copper in the chemistry. They are publishing results with stronger magnetic indications ...

In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two ...

For decades, physicists taught that superconductivity and magnetism could not share the same space. One state should destroy ...

Diamagnetism is a property of matter, superconductivity is a state of matter. Diamagnetism describes how a material reacts when plunged into a magnetic field. Paramagnetism is almost the same thing.

A Nature retraction last week has put to rest the latest claim of room-temperature superconductivity — in which researchers said they had made a material that could conduct electricity without ...

Last week, a group of South Korean physicists made a startling claim. In two papers uploaded to the arXiv preprint server, they say they have created a material that “opens a new era for humankind”.

High-temperature superconductivity is one of the holy grails of physics. It also seems to attract a steady stream of controversy, with a recent string of retracted papers and provocative claims that ...
