MH2046 Quantum Metallurgy 6.0 credits

Kvantmetallurgi

Materials science is a very fast developing subject. The ever increasing computer power allows a detailed study of materials at different spatial and temporal scales. In such a hierarchical modeling, one scale is certainly special: an atomic scale at the electronic structure level. This is the starting point for all the other scales and this is where accurate physical theory can be applied to learn what happens in materials in details, not accessible by other theoretical and experimental tools.

First-principles methods are not only standard tools for a deep-level investigation in materials science nowadays, but they are becoming an important component of an intelligent design of new materials in industry.

This course is to be considered as an INTRODUCTION into the field of first-principles calculations, with the purpose of spreading knowledge (not legends) about this type of computational tools.

The main concentration is on understanding the general idea behind first-principles methods, their weak and strong sides, solved and unsolved problems. Student will learn what kind of materials science problems can be tackled using first-principles methods and how such methods can be used.What is possible and trustable, and what is still not.
