Pj. Hirschfeld et Wo. Putikka, FINITE-TEMPERATURE POWER ABSORPTION BY COLLECTIVE MODES IN UNCONVENTIONAL SUPERCONDUCTORS, Physica. B, Condensed matter, 194, 1994, pp. 2021-2022
We calculate the power absorption due to order parameter collective mo
des in a superconducting state with E1g symmetry possibly applicable t
o UPt3, using a matrix kinetic equation approach. Close to the critica
l temperature, such features are observable as well-defined peaks in t
he absorption. At lower temperatures, however, a broad feature conside
rably larger than the normal state absorption is predicted.
