文摘

We have revisited the phase diagram of perchlorate Bechgaard salts under magnetic field at small temperature, using a spin ladder model with a Hubbard Hamiltonian. Using a non-perturbative Gor'kov method, we have calculated the free energies of all possible phases, including a phase with coexisting singlet and triplet superconducting pairs. With our choice of coupling parameters, this coexisting phase proved not favorable. Nevertheless, this study opens new fields of investigation, while the search of such a coexisting phase seems a realistic and promising goal.
