Many body methods in quantum chemistry

ABOUT THE COURSE :The course deals with the fundamental of many-body methods. We are going to derive equations starting from postulates and discuss their implication in calculation of structure, property and spectra of atoms and molecules. The course will help students working in computation physics and chemistry to make sense of their computed results.INTENDED AUDIENCE : Senior Bachelor, Master and Ph.D. students.INDUSTRY SUPPORT : Schrodinger Inc, Gaussian Inc.
