Theory of multiband superconductivity in spin-density-wave metals.
We study the emergence of multiband superconductivity with s- and d-wave symmetry on the background of a spin density wave (SDW). We show that the SDW coherence factors renormalize the momentum dependence of the superconducting (SC) gap, yielding a SC state with an unconventional s-wave symmetry. Interband Cooper pair scattering stabilizes superconductivity in both symmetries. With increasing S...
متن کاملSuperconductivity and spin-density waves in multiband metals
We present a detailed description of two-band quasi-two-dimensional metals with s-wave superconducting SC and antiferromagnetic spin-density-wave SDW correlations. We present a general approach and use it to investigate the influence of the difference between the shapes and the areas of the two Fermi surfaces on the phase diagram. In particular, we determine the conditions for the coexistence o...
متن کاملHidden fermi surface nesting and charge density wave instability in low-dimensional metals.
The concept of hidden Fermi surface nesting was introduced to explain the general observation that certain low-dimensional metals with several partially filled bands exhibit charge density wave (CDW) instabilities, although their individual Fermi surfaces do not reveal the observed nesting vectors. This concept was explored by considering the Fermi surfaces of the purple bronze AMo(6)O(17) (A =...
متن کاملSuperconductor-to-Spin-Density-Wave Transition in Quasi-One-Dimensional Metals with Ising Anisotropy
We study a mechanism for superconductivity in quasi-one-dimensional materials with Ising anisotropy. In an isolated chain Ising anisotropy opens a spin gap; if inter-chain coupling is sufficiently weak, single particle hopping is suppressed and the physics of coupled chains is controlled by a competition between pair hopping and exchange interaction. Spin density wave and triplet superconductiv...
متن کاملStability of the spin density wave phases in (TMTSF)2ClO4 : quantized nesting effect
2014 The stability of the SDW phases in (TMTSF)2ClO4 can be interpreted by simple arguments of anisotropic Fermi surfaces nesting : first, we show that anion ordering, by introducing new Bragg’s reflexions, perturbs the nesting and lowers the SDW stability. Then, we improve Gor’kov and Lebed’s argument on the effect of a magnetic field on nesting by allowing the wave vector Q(H) to adapt to the...
