“…This expectation is reinforced by the fact that the ultrasonic attenuation has been measured in the A phase, the most anisotropic of the zero-field phases. Previous calculations have indicated that the mixed representation and extended symmetry group scenarios are probably inconsistent with these measurements [8]. Accordingly we focus in this paper on the E 1g and E 2u theories.…”

“…In addition, this leads to a fit for the temperature dependence with only the single parameter ∆ 0 (T = 0). Finally, we follow Graf et al [8] in taking the empirical form for the relaxation time: τ s ≃ 0.01πT c+ (1+T 2 /T 2 c+ ).…”

We calculate the ultrasonic absorption and the thermal conductivity in the superconducting state of UPt3 as functions of temperature and direction of propagation and polarization. Two leading candidates for the superconducting order parameter are considered: the E1g and E2u representations. Both can fit the data except for the ultrasonic absorption in the A phase. To do that, it is necessary to suppose that the system has only a single domain, and that must be chosen as the most favorable one. However, the E2u theory requires fine-tuning of parameters to fit the low temperature thermal conductivity. Thus, transport data favor the E1g theory. Measurements of the thermal conductivity as a function of pressure at low temperature could help to further distinguish the two theories.

“…In these compounds, the triplet pairing can be reliably determined, for example, by Knight shift experiments [5,6], but the identification of a symmetry of the order parameter is much more difficult task. A large number of experimental and theoretical investigations done on UPt 3 and Sr 2 RuO 4 are concerned with different thermodynamic and transport properties, but the precise order parameter symmetry remains still to be worked out (see, for example, [7,[10][11][12], and original references therein).…”

Kolesnichenko Yu. A.Josephson effect in point contacts between «f-wave» superconductorsMahmoodi R., Shevchenko S. N., and Kolesnichenko Yu. A.Josephson effect in point contacts between «f-wave» superconductors A stationary Josephson effect in point contacts between triplet superconductors is analyzed theoretically for most probable models of the order parameter in UPt 3 and Sr 2 RuO 4 . The consequence of misorientation of crystals in the superconducting banks on this effect is considered. We show that different models for the order parameter lead to quite different current-phase relations. For certain angles of misorientation a boundary between superconductors can generate a spontaneous current parallel to the surface. In a number of cases the state with a zero Josephson current and minimum of the free energy corresponds to a spontaneous phase difference. This phase difference depends on the misorientation angle and may possess any value. We conclude that experimental investigations of the current-phase relations of small junctions can be used for determination of the order parameter symmetry in the superconductors mentioned above.
