Alkali-metal vibrations in bcc, fcc, hcp, and 9R structures: Implications for the energetics of Li and Na martensitic phases
D. M. Riffe, Jake D. Christensen
We present an embedded-atom-method (EAM) model that is specifically designed to accurately describe vibrations in bcc alkali metals. Using this model, we study bulk vibrational str…

Ultrafast relaxation dynamics of excited carriers in metals: Simplifying the intertwined dependencies upon scattering strengths, phonon temperature, photon energy, and excitation level
D. M. Riffe, Richard B. Wilson
Using the Boltzmann transport equation (BTE), we study the evolution of nonequilibrium carrier distributions in simple () metals, assumed to have been instantaneously excited b…

Canonical Models of Dielectric Response
D. Mark Riffe
The interaction of electromagnetic fields with a solid is characterized by several interconnected response functions: the dielectric function , index of refraction…
