| Research Abstract |
The method of particle simulation for predicting accurate thermal conductivity of insulating solids has been scrutinized in terms of the number of particles and statistical averages. Thermal conductivity using the conventional method with the phonon concept is predicted within the present framework to compare the two results, and the deviation of the phonon method from the formally exact particle method is found to grow as the temperature increases. A resonant peak is observed in the power spectrum of heat flux correlation at around 0.5THz.
