Interplay between spin-density-wave and superconducting states in quasi-one-dimensional conductors (original) (raw)

The interplay between spin-density-wave (SDW) and superconducting (SC) states in quasi-one-dimensional correlated metals is investigated using the renormalization group method. The study reveals a crossover from SDW to unconventional superconductivity when deviations from perfect Fermi surface nesting surpass a critical threshold. Findings suggest that singlet pairing between electrons on neighboring stacks is the most favorable symmetry for superconductivity, indicating the significant influence of non-uniform SDW pairing on the phase diagram within the crossover region.
