The Phonon Entropy of Transition Metals and Alloys: Effects of Impurities and of a Martensitic Phase Transition [PDF]
, 2006 For a fixed configuration of ions on a given crystalline lattice, low energy excitations around the static average configuration can be thermally activated and will contribute to the entropy of the system.

Thermalization in simple metals: Role of electron-phonon and phonon-phonon scattering [PDF]
Physical Review B, 2018 We study the electron and phonon thermalization in simple metals excited by a laser pulse. The thermalization is investigated numerically by solving the Boltzmann transport equation taking into account all the relevant scattering mechanism: the electron-electron, electron-phonon (e-ph), phonon-electron (ph-e), and phonon-phonon (ph-ph) scatterings.
