Effective potential for femtosecond-laser-excited silicon — •Bernd Bauerhenne, Eeuwe S. Zijlstra, and Martin E. Garcia — Theoretische Physik - Universität Kassel, Heinrich-Plett-Str. 40, 34132 Kassel, Germany

Effective potentials are a powerful tool for modeling femtosecond-laser materials processing where the spatial geometry of the laser is important and therefore a huge number of atoms must to be taken into account, like, ablation or spallation. Here we present a new effective potential for femtosecond-laser-excited silicon, which we test by accurately reproducing the physics of ultrafast melting.
