In metals, thermal conduction results from the motion of free electrons, and there is close correspondence between thermal conductivity and electrical conductivity. In solids that are poor conductors of electricity and in most liquids, thermal conduction results from momentum transfer between adjacent vibr...
In this work, the thermal conductivity is calculated using a kinetic equation for the first time. This calculation is valid at low ( T e T F = E F / k B , where E F is the Fermi energy and k B is the Boltzmann constant) and moderate ( T e < T F ) temperatures. The earlier...

The low-temperature thermal conductivity of metals containing quantum thermalized defects is investigated. It is shown that the main contribution to the thermal conductivity is due to electrons scattered from such defects and the temperature dependence of thermal conductivity κ is determined. The effect...
Measurements are reported on the thermal conductivity, λ, of various Cu, Ag and Al samples in the kelvin temperature range, as well as of Cu and of superconducting Al in the millikelvin temperature range. For Cu it was found that λα T and there was agreement with the Wiedemann-Franz la...
