Superconducting Energy Gap Structure of CsVSb from Magnetic Penetration Depth Measurements
Morgan J Grant, Yi Liu, Guang-Han Cao +4
Experimental determination of the structure of the superconducting order parameter in the kagome lattice compound CsVSb is an essential step towards understanding the natur…
Observation of the Non-linear Meissner Effect
J. A. Wilcox, M. J. Grant, L. Malone +9
A long-standing theoretical prediction is that in clean, nodal unconventional superconductors the magnetic penetration depth , at zero temperature, varies linearly with magnetic…
Full-gap superconductivity robust against disorder in heavy-fermion CeCu2Si2
T. Takenaka, Y. Mizukami, J. A. Wilcox +9
A key aspect of unconventional pairing by the antiferromagnetic spin-fluctuation mechanism is that the superconducting energy gap must have opposite sign on different parts of the…
Fully gapped superconductivity with no sign change in the prototypical heavy-fermion CeCu2Si2
T. Yamashita, T. Takenaka, Y. Tokiwa +16
In exotic superconductors including high- copper-oxides, the interactions mediating electron Cooper-pairing are widely considered to have a magnetic rather than the convention…
