Learning goals
After completion of this course, the student should be able to:
i) assess all factors that affect the accuracy of MD simulations; ii) understand the algorithms and computational cost of MD simulations; iii) assess the quality of sampling and of the methods used to improve sampling; iv) set up classical or ab-initio MD simulations; v) set up free energy calculations; vi) analyse structural and dynamical properties. The following competences will also be developed: - Competence in analysis and synthesis; - Competence in problem solving; - Competence in critical reasoning; - Competence in autonomous learning; - Competence in research. Syllabus
Statistical mechanics review: ensembles, fluctuations, correlation functions and transport coefficients.
Empirical and semi-empirical pair- and inter-molecular potentials. Classical molecular dynamics: equations of motion, simulation initialisation, algorithms for integration of the equations of motion, Liouville formulation. Simulations at constant temperature or pressure: Andersen and Nosé-Hoover thermostats and barostats. Free-energy calculations: thermodynamic integration, chemical potential, Gibbs ensemble, free energies of solids, non equilibrium systems. Technical details: long-range interactions, rare events, supercomputers. Ab-initio molecular dynamics: Born-Oppenheimer, Ehrenfest, Car-Parrinello, QM/MM. Applications. Prerequisites
Classical Mechanics, Thermodynamics, Quantum Mechanics

The subject matter will be presented in the theoretical classes. These presentations will be complemented with practical and theoretical problems given as homework and discussed afterwards in the tutorial classes.
