Aims
On the basis of numerical simulations, study of materials at the time and space scales corresponding to electronic and molecular phenomena
Main themes
Detailed presentation of simulation techniques valid for all kinds of materials (metals, semiconductors, ceramics, polymers). A series of exercices, tuned towards real materials, allows to apply, thanks to computers, the concepts developed in the Physics of Materials lectures.
Content and teaching methods
Lectures " ex cathedra " : presentation of the concepts
Exercices : the student learns to use different simulation softwares. Then, he/she chooses a topics, studies it, and write a report, that constitutes the main part of the evaluation.
Content of lectures.
A.General presentation of simulation methods
(based on examples, one motivates the use of simulation techniques in material science : very brief, but exhaustive, presentation of different methods ; presentation of physical concepts connected to algorithmic and visualisation techniques, and relations with experimental data)
B.Classical molecular simulations
(empirical or semi-empirical interaction potentials ; molecular dynamics ; search for the equilibrium state ; damped dynamics ; canonical ensemble simulation ; thermostats)
C.Tight-binding simulations
(semi-empirical parametrisation of the hamiltonian ; resolution algorithms ; diagonalisation ; recursion method)
D.Ab Initio simulations
(introduction to Ab Initio techniques ; elements of density functional formalism ; plane wave basis and pseudopotentials ; iterative algorithms)
E.Vibrational and optical properties : theory and simulation
(dielectric tensor, phonons, electronic excitations, photon-phonon interaction, non-linear effects)
