Abstract

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.
