Analytical and Numerical Verification of the Nernst Theorem for Metals
Johan S. Høye, Iver Brevik, Simen A. Ellingsen, Jan B. Aarseth
abstract: In view of the current discussion on the subject, an effort is made to show
very accurately both analytically and numerically how the Drude dispersion
model gives consistent results for the Casimir free energy at low temperatures.
Specifically, for the free energy near T=0 we find the leading term to be
proportional to T^2 and the next-to-leading term proportional to T^{5/2}. These
terms give rise to zero Casimir entropy as T approaches zero, and is thus in
accordance with Nernst's theorem.
