How to determine pairing symmetry of quasi-1D organic superconductors through magnetotunneling spectroscopy

Application of magnetic fields is proposed to be a good way of discriminating anisotropic p-, d-, and f-wave pairing symmetries from tunneling spectra in a model quasi-1D superconductor (TMTSF)2X. The shape of the Fermi surface affects sensitively the shape of the gap along with the presence/absence...

Summary:Application of magnetic fields is proposed to be a good way of discriminating anisotropic p-, d-, and f-wave pairing symmetries from tunneling spectra in a model quasi-1D superconductor (TMTSF)2X. The shape of the Fermi surface affects sensitively the shape of the gap along with the presence/absence of the Andreev bound states, where the magnetic field further probes the gap function through the Doppler shift. Thus the magnetotunneling spectroscopy is promising in distinguishing the pairing symmetry in (TMTSF)2X.
