Learning goals

Specific skills:

The student should get an in-depth knowledge about the electronic structure of atoms, molecules and solids and become familiar with the most common techniques for ab-initio calculations - and be aware of the approximations involved in such calculations.

He/she should be able to solve specific problems involving electronic structure calculations using modern computational tools (such as GAMMESS and OCTOPUS codes)

Generic goals:

This student should be able to search, with guidance, for relevant bibliographic references and become familiar with the state of the art theoretical and computational techniques for electronic structure calculations.

Generic skills:

The student should develop analytical and problem solving skills, and critical reasoning while tackling specific problems. He/she should be able to organize and plan the best strategies and apply the most appropriate analytical or computational tools, in a creative way, to problems and analyse the results.

Teaching method

During the lectures, the main theory topics will be presented to the student, that will be illustrated, whenever possible, with practical examples. A few mathematical demonstration will not be made during the lectures but will be left for the student to complete at home, following recommended bibliography. These small theory problems will count for the student evaluation, in addition to the assigned computational problems.
