New Physics in the Old Molecular Superconductors

Abstract: The 1D organic superconductors have been around
for two decades now, but the nature and symmetry of the pairing state are
as yet ill-determined. We'll report on the status of our experiments
addressing, with the obvious goal of settling, the issue. These include
transport and magnetic determinations of upper critical fields, susceptibility
in the superfluid phase via the Knight shift, and schemes for symmetry
probes. The short story is that the superconducting state is most
assuredly unconventional and probably equal spin triplet, as the Clogston
limit is exceeded by several hundred per cent. In fact, superconductivity
has not been suppressed yet in our highest field data.
