Kapitza Resistance

Kapitza Resistance

Kapitza Resistance

(OP)
When heat is conducted from a solid into liquid helium, a thermal boundary resistance occurs across the interface. This effect, known as Kapitza resistance, has been studied since the original experiments were conducted in 1941. To the best of my knowledge, the most accurate model of Kapitza resistance is the acoustic impedence theory. This theory if usually off by one or more orders of magnitude in predicting the value of the thermal boundary resistance. Have there been any theories proposed in the last 5 years that do a better job of predicting the thermal boundary resistance? Have there been any advances in our understanding of this phenomenon?
