Scientists have achieved a major milestone in the quest to understand high-temperature superconductivity in hydrogen-rich ...

This indicates that the parts of the Fermi surface remain ungapped deep in the superconducting state. Eventually a gap opens ...

Ultra-low-temperature scanning tunnelling spectroscopy measurements indicate that twisting the layers in heterostructures making up a single layer of superconducting NbSe 2 on graphene leads to ...

Typically, a superconductor's energy gap is the same at all locations within the material. For example, in a superconducting crystal without impurities, all pieces of the crystal would have the ...

In conventional superconductors, electron pairs (i.e., Cooper pairs) form due to phonon-mediated interactions, resulting in a superconducting gap that follows an isotropic s-wave symmetry.

By adjusting the twist angle, they were able to finely tune the “superconducting gap,” which plays a key role in the behavior of these materials. The research was published in Nature Physics. The ...
