Abstract
This work is devoted to classical molecular dynamics simulations of surface modifications (craters)
drilled by single femtosecond laser pulses or ultrashort XUV pulses in silicon and diamond, materials
relevant for numerous industrial applications. We propose a methodology [1] paving the way towards a
significant decrease in the simulation computational costs, which could also enable a precise estimation
of the craters’ size and shape.

Vladimir Lipp finished his PhD at the University of Kassel (Germany) in 2015, then from 2016 to 2021 worked as a postdoc at the Center for Free-Electron-Laser Science (CFEL), DESY, Hamburg (Germany), and since 2021 he is a postdoc at the Institute of Nuclear Physics, Polish Academy of Sciences, Krakow, Poland. He applies continuum modeling, classical molecular dynamics, Monte Carlo, Tight Binding, Density Functional Tight Binding simulations to study how optical and XUV lasers influence various material properties, including damage studies.
