Superconductivity is an advantageous physical phenomenon observed in some materials, which entails an electrical resistance ...

For two layers of graphene, her team found that the superconducting current is much “stiffer” – it resists change more – than is predicted by any conventional theory of superconductivity.

Lauren Petracca for The New York Times Superconductivity was discovered by Heike Kamerlingh Onnes, a Dutch physicist, and his team in 1911.

Image Credit: Caltech Institute of Technology Caltech engineers have demonstrated that one of these remarkable materials, tungsten diselenide, is not just a competitor but also an addition to graphene ...

Now Jarillo-Herrero and his team have shown that superconductivity in magic-angle graphene can be switched on, and kept on, with just a short pulse rather than a continuous electric field. The key, ...

Superconductivity seems to run in the family as far as graphene is concerned. An illustration showing superconducting Cooper pairs in magic-angle multilayer graphene family. The adjacent layers are ...

Since superconductivity in three-layered graphene was discovered in September, the physics community has been left puzzled. Now, three months later, physicists from IST Austria together with ...

Read the paper: Superconductivity in rhombohedral trilayer graphene To understand more about these phases, Zhou et al. studied the system’s response to in-plane and out-of-plane magnetic fields.

This behavior is not seen in conventional spin-singlet superconductors. The reintroduced superconductivity lasted in the magic-angle trilayer graphene up to a magnetic flux of 10 Tesla, but this was ...

Physicists at MIT have conducted a study on a material called magic-angle twisted trilayer graphene. The material has exhibited signs of a rare type of super connectivity. Physicists at MIT ...
