Overview

This course introduces advanced concepts of quantum mechanics at the final level of a bachelor's degree programme. It covers a range of topics starting from Separation of the Schrödinger equation in spherical coordinates, a particle in a spherical potential well and the hydrogen atom, associated Lager polynomials, Dirac notation, Hilbert spaces, Eigenfunctions and Eigenvalues and orbital angular momentum ending with approximation methods.

Intended learning outcomes

By studying the course, the student will be able to:1. The wave function is used to calculate the expected values of physical quantities such as orbital angular momentum and its components using the effects of a three-dimensional system..2. Apply the Schrödinger equation to find the eigenfunctions and eigenvalues of different three-dimensional quantum systems.3.
