Nonuniversal critical phenomena along the lambda line of4He

II. Thermal conductivity in three dimensions


We present a new calculation of the critical thermal conductivity near the lambda line of4He. Static and dynamic effects are properly separated and are calculated within modelF in three dimensions by means of renormalized field theory up to two-loop order. The result provides an appropriate basis for analyzing forthcoming thermal conductivity data and for determining the temperature and pressure dependence of the effective dynamic parameters of4He in the entire critical region. This can be used to predict other nonuniversal dynamic critical phenomena above and below the lambda line.
