Abstract:

Superconductivity is a low-temperature phenomenon in the solid state where electricity can flow without resistance. The microscopic building blocks are two-electron "molecules", so-called Cooper pairs. This destabilizes the low-energy electronic states, opening a "gap" in the electron spectrum. The form of the gap reflects the way that the electrons bind into Cooper pairs, and is therefore a critical piece of information in building up a microscopic understanding of the superconductivity. Up to now three types of gap were thought possible: a full gap, or a gap which vanishes at point or line nodes, allowing a classification in terms of angular-momentum eigenstates, the so-called spherical harmonics. We have recently demonstrated that a fourth type of gap exists, which vanishes on a surface. This unique gap structure arises from an additional degree of freedom of the electrons in the Cooper pair due to the atomic orbitals from which the electrons ultimately originate. We expect that this gap structure could arise in certain exotic Uranium-based compounds.
