Abstract

We calculate the nonadiabatic contributions to the free energy of metals due to the electron-phonon interaction at intermediate temperatures, $0 ⩽ k_{B} T < ϵ_{F}$ for four different nearly free electron metals, Na, K, Al, and Pb. We calculate its value for $T = 0$ which has not been calculated before and we study its low temperature behavior.
