Non--Adiabatic Contributions to the Free Energy from the Electron--Phonon Interaction for Na, K, Al, and Pb

N. Bock, D. Coffey, Duane C. Wallace

We calculate the non--adiabatic contributions to the free energy of metals due to the electron--phonon interaction at intermediate temperatures, $0⩽k_{B}T<{\epsilon }_F$ for f…
