Thermal conductivities of helium 3 and 4 across the lamda point?

22 September 2024 1 4K Report

Could someone please give me some information about the thermal conductivities of helium 3 and helium 4 at temperatures measured in millikelvins?

Pedro L. Contreras E.

Dear Prof. Saheb Paramanik

The book: "Near The Absolute Zero" by Prof. V. Edelman from MIR publisher (1983) gives an answer in chapter six for the superfluid isotope 4He and in chapter 7 for the isotope 3He.

The thermal conductivity of these two isotopes of Helium is elegantly explained in this book.

Best Regards.
