Order parameter of quasi-one-dimensional superconductors: symmetry features in quasiparticle density of states and spin susceptibility

Abstract

Recent experiments indicate that the Bechgaard salts (TMTSF)${}_2$ ClO${}_4$ and (TMTSF)${}_2$ PF${}_6$ may be unconventional triplet superconductors. The quasiparticle density of states and the uniform spin susceptibility tensor are computed at low temperatures for order parameter symmetries, as an attempt to narrow the number of possibilities based on experimental evidence.
