S- and D-wave Pairing in Short Coherence Length Superconductors
Over the past three years or so the evidence has become overwhelming that the cuprate high Tc superconductors have a d-wave pairing state[1]. The measurements of Wollman et al.[2] and of Tsuei et al.[3] are especially convincing since they do not depend on the microscopic physics of the energy gap, but instead depend only on the order parameter phase. Other experiments, such as photoemission[4,...
متن کاملS-wave pairing symmetry in non-centrosymmetric superconductor Re3W
The alloys of non-centrosymmetric superconductor, Re3W, which were reported to have an α-Mn structure [P. Greenfield and P. A. Beck, J. Metals, N. Y. 8, 265 (1959)] with Tc = 9 K were prepared by arc melting. The ac susceptibility and low-temperature specific heat were measured on these alloys. It is found that there are two superconducting phases coexisting in the samples with Tc1 ∼ 9 K and Tc...
متن کاملCorrelation between characteristic energies in non–s-wave pairing superconductors
By solution of the Bethe-Goldstone equation for the Cooper pairing problem, an approximate analytic relation is derived between coherence length ξ and the binding energy of the Cooper pair. This relation is then qualitatively confirmed by numerically solving the corresponding self-consistent gap equations, following the crossover from weak to strong coupling, in non–s-wave superconductors. The ...
متن کاملBoson induced s-wave pairing in dilute boson-fermion mixtures
We show that in dilute boson-fermion mixtures with fermions in two internal states, even when the bare fermion-fermion interaction is repulsive, the exchange of density fluctuations of the Bose condensate may lead to an effective fermion-fermion attraction, and thus to a Cooper instability in the s-wave channel. We give an analytical method to derive the associated Tc in the limit where the pho...
متن کاملExotic s-wave superconductivity in alkali-doped fullerides.
Alkali-doped fullerides (A3C60 with A = K, Rb, Cs) show a surprising phase diagram, in which a high transition-temperature (Tc) s-wave superconducting state emerges next to a Mott insulating phase as a function of the lattice spacing. This is in contrast with the common belief that Mott physics and phonon-driven s-wave superconductivity are incompatible, raising a fundamental question on the me...
