Aims

To introduce the formalism and foundational concepts of quantum mechanics.


Learning Outcomes

(LO1) Demonstrate an understanding of how quantum systems are described by wave functions, and how probabilities are extracted.

(LO2) Solve the Schrödinger Equation and describe the properties of a particle confined to fundamental potentials.

(LO3) Demonstrate an understanding of operators and eigenvalue problems in quantum mechanics and apply knowledge to solve simple problems.

(LO4) Understand how orbital angular momentum and spin angular momentum are described in quantum mechanics and apply knowledge to solve simple problems.

(LO5) Demonstrate an understanding of how quantum mechanics can be used to describe the Hydrogen atom, including fine structure.

(LO6) Describe and explain the structure of the periodic table and how this relates to Pauli’s Exclusion Principle.

(LO7) Solve one-dimensional problems involving scattering, transmission, reflection, and tunnelling of quantum probability amplitudes.

(S1) Problem solving skills

(S2) Collaborative learning
