Ci. Um et al., ANOMALOUS PHONON-SPECTRA IN BULK AND THIN LIQUID HE-II .2. APPLICATIONS TO KINETIC COEFFICIENTS, Journal of the Korean Physical Society, 28, 1995, pp. 255-259
Using the zero-temperature and temperature-dependent elementary excita
tion spectra obtained in the previous paper (hereafter, referred to Pa
per I), we evaluate the temperature dependence of kinetic coefficients
-thermal conductivity, first and second viscosity-in pure liquid He II
and dilute He-3-He-4 mixtures. In all the coefficients, three phonon
processes, which can be possible only in the anomalous phonon spectrum
, are the important phonon processes at low temperatures and pressures
. By considering these processes explicitly, we obtain the considerabl
e improvements for all the coefficients.
