Computational physics and chemistry at the Kumpula Campus

I will first present what the role of computer simulations are in physics, namely how they relate to theoretical and experimental physics. I will then give an overview of computational physics and chemistry activities on our campus, showing that simulations have an important role in almost all active research areas. To give an idea of what computer simulations of processes occuring in nature may mean in practise, I present three central algorithms used widely in different branches of physics and chemistry: Metropolis Monte Carlo, Kinetic Monte Carlo and Molecular dynamics. I also point out that especially the first of these is also widely used in mathematics and computer science, even though it was originally devised to simulate a problem very much belonging to physics only, the melting of a hard sphere system. Finally I will present some results of recent research in our group on how molecular dynamics can be used to understand how the properties of a new nanomaterial, carbon nanotubes, can be improved on by ion irradiation.
