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.

“…We can drive the motion of the normal component and detect the energy loss simultaneously by using the fourth sound resonance. In pure liquid 3 He (without aerogel), the motion of the normal component is well understood by the hydrodynamic theory including the slip effect [4,5]; the energy loss of the fourth sound propagating in pure 3 He confined in the narrow pore is represented as,…”

“…The slip length is a phenomenological parameter introduced as a correction to the hydrodynamic boundary condition and is of the order of the mean free path. 26,27 Around 100 mK, the slip length is ∼10 nm and the penetration depth is ∼1 µm. Therefore in this experiment r ∼ 10 −2 ≪ 1 and k 1i and k 2i are at least two orders of magnitude smaller than the other terms in Eq.…”

A micro-electro-mechanical system vibrating in its shear mode was used to study the viscosity of normal liquid 3 He from 20 mK to 770 mK at 3 bar, 21 bar, and 29 bar. The damping coefficient of the oscillator was determined by frequency sweeps through its resonance at each temperature. Using a slide film damping model, the viscosity of the fluid was obtained. Our viscosity values are compared with previous measurements and with calculated values from Fermi liquid theory. The crossover from the classical to the Fermi liquid regime is manifest in the temperature dependence of viscosity. In the Fermi liquid regime, the temperature dependence of viscosity changes from T −1 to T −2 on cooling, indicating a transition from the Stokes flow to the Couette flow regime.
