indicates that superconductivity is robust against impurities, implying that there is no sign change in the gap function. These results show that, contrary to long-standing belief, heavy electrons with extremely strong Coulomb repulsions can condense into a fully gapped s-wave superconducting state, which has an on-site attractive pairing interaction.
FingerprintDive into the research topics of 'Fully gapped superconductivity with no sign change in the prototypical heavy-fermion CeCu2Si2'. Together they form a unique fingerprint.
