“…This was actually the motivation for Pethick and Pines [17] to apply the t-matrix to the description of transport in heavy Fermion superconductors, since the experiments showed transport parameters vanishing at low T instead of staying constant below T c . It is quite amazing, that the T -dependence of Y (1) aa (T ) is close to the power laws T 3.5 in the B 1g -and T 1.5 in the B 2g -case, as predicted by Moreno and Coleman for the ultrasound attenuation [26]. In Fig.…”

“…During the last few decades a large variety of so-called unconventional superconductors have been discovered, among these the superfluid phases of 3 He [1][2][3][4], the heavy Fermion systems [5][6][7], the cuprates [8,9] and the Ruddlesden-Popper system Sr 2 RuO 4 [10]. The unconventional pairing correlations in these systems manifest themselves on the one hand in an anisotropy of the pair potential or energy gap of less symmetry than the underlying band structure or in the occurrence of additional spontaneously broken symmetries besides the U (1) gauge symmetry.…”

We investigate the collision-limited electronic Raman response and the attenuation of ultrasound in spin-singlet d-wave superconductors at low temperatures. The dominating elastic collisions are treated within a t-matrix approximation, which combines the description of weak (Born) and strong (unitary) impurity scattering. In the long wavelength limit a two-fluid description of both response and transport emerges. Collisions are here seen to exclusively dominate the relaxational dynamics of the (Bogoliubov) quasiparticle system and the analysis allows for a clear connection of response and transport phenomena.When applied to quasi-2-d superconductors like the cuprates, it turns out that the transport parameter associated with the Raman scattering intensity for B 1g and B 2g photon polarization is closely related to the corresponding components of the shear viscosity tensor, which dominates the attenuation of ultrasound. At low temperatures we present analytic solutions of the transport equations, resulting in a non-power-law behavior of the transport parameters on temperature.

“…The relevance of ferromagnetic fluctuations [62], [63] for anisotropic BCS states was illustrated by the p wave superfluidity of liquid 3 He [64]. The p wave T C in nearly ferromagnetic metals was first calculated in 1971 [65] and in both FM and PM phases in 1980 [66].…”

The interplay of magnetism and unconventional superconductivity (d singlet wave or p triplet wave) in strongly correlated electronic system (SCES) is discussed with recent examples found in heavy fermion compounds. A short presentation is given on the formation of the heavy quasiparticle with the two sources of a local and intersite enhancement for the effective mass. Two cases of the coexistence or repulsion of antiferromagnetism and superconductivity are given with CeIn 3 and CeCoIn 5 . A spectacular example is the emergence of superconductivity in relatively strong itinerant ferromagnets UGe 2 and URhGe. The impact of heavy fermion matter among other SCES as organic conductor or high T C oxide is briefly pointed out.

“…Research on the subject then exploded following the unexpected discovery 8 in 1972 of this superfluid at temperatures below 0.003 K. At first, the observations were interpreted as spontaneous nuclear magnetic ordering in solid helium-3, but shortly afterwards, they were correctly identified as the transition to a superfluid 9 . Nuclear magnetic ordering in solid helium-3 was discovered 10 two years later at a temperature of 0.001 K.…”
