Rationale and Purpose of the Module:

The pupose of the module is to extend the students understanding of quantum mechanics and to introduce students to applications of quantum mechanics in solid state physics.

Syllabus:

Review of Schrodinger picture: barriers, wavepackets, scattering. Formalism: linear operators, harmonic oscillator, Dirac notation, postulates, the uncertainty principle. Quantum mechanics in three dimensions: the hydrogen atom, angular momentum, spin. Time independent perturbation theory: spin-orbit coupling, the Zeeman effect. The variational principle: the ground state of helium. Bonding: the hydrogen molecule, molecular orbitals. The WKB approximation: tunnelling. Energy bands: Bloch theorem, Kronig-Penney model, nearly free electron model, the tight binding model. Time dependent perturbation theory: two level systems, emission and absorption of radiation, spontaneous emission.

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

- Explain the fundamental concepts and foundations of quantum mechanics. - Discuss the application of quantum mechanics to the hydrogen atom. - Discuss approximate methods of solution in applications of quantum mechanics. - Discuss the application of quantum mechanics to bonding, orbitals and energy bands. - Derive relevant equations describing quantum systems, from basic laws and principles. - Solve numerical problems from information provided on the topics covered.
