What To Expect:

This 2-week intensive course aims at senior undergraduate, graduate, and postdoctoral scholars. Attendees will be introduced to:

  • the theoretical background of powerful modern molecular dynamics and Monte-Carlo schemes,
  • predictive quantum-mechanical approaches such as density functional theory,
  • hands-on experience with Python coding, visualization, and running own simulations using freely available open-source software packages.

 

Morning lectures provide theoretical background and afternoons are for hands-on practice and implementation in computer labs. This combination conveys good understanding of all theoretical approaches. Attendees will develop their own ideas for a toy problem, implement small parts of code if necessary, run simulations, and write a short report on results and obstacles encountered.

Course Description:

This class covers computational techniques for microscopic systems ranging from a few up to millions of atoms. Molecular dynamics provides exciting insight into the dynamic aspect of thermodynamic phase-space averages. Important concepts, such as potential-energy surfaces, classical potentials, and their quantum-mechanical foundation will be outlined. Connections to accurate, computationally expensive methods, e.g.  those based on density functional theory will be pointed out. Furthermore, this class covers probabilistic Monte-Carlo techniques, that differ conceptually: The idea of probabilistic integration, Markov-Chain approaches, and Metropolis Monte-Carlo will be presented. Examples for practical applications of the different techniques are discussed throughout.
