 New Physics in the Old Molecular Superconductors

Michael J. Naughton

(Department of Physics, Boston College)

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.
