Kapitza Resistance Near 1 mK — The Shaking Box Model
It is postulated that the dominant vibrational modes of a sintered heat exchanger in the temperature range 1 to 20 mK are localised oscillations of the powder particles. The energy transfer between 3He in the pores of the sinter and these sinter oscillations is then calculated and yields good agreement with experimental results.
