9 SCIENTIFIC HIGHLIGHT OF THE MONTH Correlated Electron-Ion Dynamics

Correlated Electron-Ion Dynamics (CEID) is an extension of molecular dynamics that allows us to introduce in a correct manner the exchange of energy between electrons and ions. The formalism is based on a systematic approximation (Small Amplitude Moment Ex-pansion- SAME). This formalism is introduced, including modications to account for open boundaries, its structure analysed, and some results given (the heating of an ion by current carrying electrons, and inelastic I-V spectroscopy). The computer code that implements the closed system version of the formalism (Dinamo) is described. We close with some thoughts about the future prospects of this approach. 69
