Aims

To discuss mathematically the wave theory of matter by analysing the Schrodinger equation and introduce basic operator algebra and quantum-mechanical postulates.


Module Summary

Quantum mechanics is the theoretical framework used to describe the most fundamental properties of matter. It has a rich mathematical structure and it has provided the impetus for many advances in mathematics. It also has many practical applications, including the modelling of atoms, molecules and semiconductors. Recently, quantum theory has been used extensively to model superfluids and supercooled gases, and there are even attempts to build computers which function by the laws of quantum mechanics.

This module discusses the wave formulation of quantum mechanics in the context of the one-dimensional Schrodinger equation, which is mathematically solved in various trapped problems, including box and quadratic potentials, and open-boundary cases. The course introduces the more mathematical aspects of quantum mechanics including its formal structure based on the fundamental postulates, and the role and importance of operator algebra in describing such systems. Simple extensions to three dimensions are also touched upon, including a brief discussion of relevant quantum numbers.

Outline Of Syllabus

Reminder of Preliminary concepts: de Broglie and Planck relations and the uncertainty principle; brief introduction to distribution functions. Schrodinger's equation and its solutions in an infinite- and finite-height box and in a harmonic oscillator potential; the correspondence principle and superposition states. The formal rules of quantum mechanics: basic postulates, operator algebra; the harmonic oscillator revisited. Open boundary problems, reflection and transmission coefficients. Basic introduction to the 3D Schrodinger equation.

Assessment Rationale And Relationship

A substantial formal unseen examination is appropriate for the assessment of the material in this module. The coursework assignments allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose as well as their primary summative purpose.

In the event of on-campus examinations not being possible, an on-line alternative assessment will be used for written examination 1.
