Objectives

To understand the inadequacy of classical concepts in the interpretation of some experimental results and the need for a new formulation of physics. To introduce wave mechanics, making applications to one-dimensional systems. To understand the atomic structure and atomic processes. To Study applications of quantum physics in astrophysics, condensed matter and/or optics.

Learning outcomes and competences
