Advanced Boundary Conditions for the Simulations of Laser Ablation
Eugen Eisfeld, Dominic Klein, Johannes Roth
Irradiating materials with ultra-short laser pulses generates unwanted shock waves which distort the interesting physics. Advanced boundary conditions are presented to erase even v…
Laser Ablation of Al-Ni Alloys and Al-Ni Layer Systems simulated with Molecular Dynamics and the Two-Temperature Model
Dennis-Michael Rapp, Alexander Kiselev, Hans-Rainer-Trebin +1
Laser ablation of Al-Ni alloys and Al films on Ni substrates has been studied by molecular dynamics simulations (MD). The MD method was combined with a two-temperature model to des…
Classical interaction potentials for diverse materials from ab initio data: a review of potfit
Peter Brommer, Alexander Kiselev, Daniel Schopf +3
Force matching is an established technique to generate effective potentials for molecular dynamics simulations from first-principles data. This method has been implemented in the o…
Simulation of Laser Ablation in Aluminum: The Effectivity of Double Pulses
Johannes Roth, Armin Krauß, Jan Lotze +1
Lasers are becoming a more and more important tool in cutting and shaping materials. Improving precision and effectivity is an ongoing demand in science and industry. One possibili…
Statistical investigations on nitrogen-vacancy center creation
Denis Antonov, Timo Häußermann, Andrew Aird +10
Experiments show that shallow nitrogen implantations (<10keV) result in a negatively charged nitrogen-vacancy center (NV-) yield of 0.01-0.1%. The most succesful technique for intr…
Influence of polarizability on metal oxide properties studied by molecular dynamics simulations
Philipp Beck, Peter Brommer, Johannes Roth +1
We have studied the dependence of metal oxide properties in molecular dynamics (MD) simulations on the polarizability of oxygen ions. We present studies of both liquid and crystall…
