Overview

This course aims to give the students competence in the methods and techniques of calculations using computers. At the end of the course the student is expected to have a hands on experience in modeling, algorithm development, implementation and calculation of physical quantities of relevance in interacting many body problems in physics. Both quantum and classical computational tools will be introduced.
INTENDED AUDIENCE: Masters students in physics, engineering physics students and scientists interested in quantum and/OR molecular modelling.PREREQUISITES: Basic Statistical Physics and quantum mechanics.INDUSTRY SUPPORT: Shell, Unilever,TCS
