Subject Description

Quantum mechanics governs the structure of atomic, molecular and solid state systems, the nature of light and charge, and the interactions between these systems. Whereas earlier subjects detailed the principles and foundations of quantum mechanics, this subject details properties of real systems and discusses applications of this fundamental field of enquiry. The necessary use of quantum ideas in developing an understanding of the structure of matter is emphasised. The content of this subject includes aspects of the following: systems of identical particles, symmetrisation and antisymmetrisation, the Pauli Exclusion Principle and applications; the helium atom; degenerate perturbation theory; an introduction to many-electron atoms; fine and hyperfine structure; atoms in static external fields, the Stark and Zeeman effects, magnetism; time-dependent perturbation theory, electromagnetic transitions in atoms, spectroscopy and lasers; exponential decay and barrier penetration; an introduction to molecules and chemical bonds; crystal bonding and structure; crystal imperfections and mechanical properties; lattice vibrations and thermal properties; band theory of electrons: metals, insulators and semiconductors; dielectric and magnetic properties of solids; superconductivity.

Assessment

A 3 hour end-of-semester written examination, plus tests and/or assignments, set during the semester, which may account for up to 20% of the final mark.
