“…Based on the same pairing model, we previously investigated the nuclear spin-lattice relaxation rate to explain peculiarities observed in T −1 1 . 23,24,25 In this paper, we calculate the superfluid density and demonstrate that this pairing model gives simultaneously an explanation of the powerlaw temperature dependence of the penetration depth at low temperatures in CePt 3 Si. This paper is organized as follows.…”

For a noncentrosymmetric superconductor such as CePt3Si, we consider a Cooper pairing model with a two-component order parameter composed of spin-singlet and spin-triplet pairing components. We calculate the superfluid density tensor in the clean limit on the basis of the quasiclassical theory of superconductivity. We demonstrate that such a pairing model accounts for an experimentally observed feature of the temperature dependence of the London penetration depth in CePt3Si, i.e., line-node-gap behavior at low temperatures.

“…The explicit form of the Eilenberger equations which will be given here Eqs. (A.10) and (A.13) would be useful for future studies in inhomogeneous systems such as surfaces, junctions, and vortices 24,53 in the noncentrosymmetric superconductor. We start with the Eilenberger equation given in Eq.…”

Nuclear magnetic relaxation and superfluid density in Fe-pnictide superconductors: an anisotropic ±s-wave scenario

We discuss the nuclear magnetic relaxation rate and the superfluid density with the use of the effective five-band model by Kuroki et al. [Phys. Rev. Lett. 101, 087004 (2008)] in Fe-based superconductors. We show that a fully-gapped anisotropic ±s-wave superconductivity consistently explains experimental observations. In our phenomenological model, the gaps are assumed to be anisotropic on the electron-like β Fermi surfaces around the M point, where the maximum of the anisotropic gap is about four times larger than the minimum.
