Abstract:
Recent theories of superconductivity based on the exchange of AFM spin-fluctuations argue for an
unconventional spin-singlet order parameter with dx2 - y2
symmetry. One important feature of this state is that the excitation gap has nodal lines on the Fermi
surface. We show that the low-energy quasiparticle states near the nodes give rise to characteristic
anomalies in the surface impedance which can be used to locate the positions of the nodes of an
unconventional gap in momentum space.
