Uniform spin susceptibility tensor and quasiparticle density of states in organic quasi-one-dimensional superconductors

We perform calculations relating the order parameter symmetry of organic quasi-one-dimensional superconductors to the bulk quasiparticle density of states and the bulk uniform spin susceptibility tensor at finite temperatures. Current experimental results suggest that some organic quasi-one-dimensional superconductors may exhibit triplet pairing symmetry. The purpose of our analysis is to attempt to narrow down the number of possibilities for the symmetry of the order parameter based on the experimental evidence.
