Physicist. Current interests where I use LAMMPS are strongly related to the stress dynamics in crystals / dislocations / high entropy alloys. LAMMPS is a sort of laboratory for me, an experimental tool. I use it not so much for finding “real” properties of materials. I use it rather to test physical / mathematical models of matter. See for instance: https://iopscience.iop.org/article/10.1088/2399-6528/adcdbf
