Quantum and statistical mechanics of matter

Our universe is full of matter, but the laws needed to explain this matter are complicated. In this module, you’ll learn some advanced tools from quantum and statistical mechanics, and use them to unveil the properties and behaviour of atoms, molecules and exotic states of matter. You’ll learn to navigate complex problems using approximations to the physics of many-electron systems, such as atoms and molecules and their interactions with electromagnetic fields. You’ll also discover how statistical mechanics can describe exotic matter, such as Bose–Einstein condensates and the complex interactions leading to magnetic materials.

Credits

Credits

  • Credits measure the student workload required for the successful completion of a module or qualification.
  • One credit represents about 10 hours of study over the duration of the course.
  • You are awarded credits after you have successfully completed a module.
  • For example, if you study a 60-credit module and successfully pass it, you will be awarded 60 credits.

Study level
Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU postgraduate modules correspond to these frameworks.

What you will study

This module comprises three parts.

Parts one and two are based on Physics of Atoms and Molecules by Bransden and Joachain. Part three is based on Topics in Statistical Mechanics by Cowan. Notes and video lectures guide you through the material in the books. There will also be tutorials to guide you through problem-solving.

Part 1
The first part covers the application of quantum mechanics to the interaction of hydrogen with electromagnetic fields. It begins with a review of quantum mechanical fundamentals and continues to describe the interactions between electromagnetic radiation and atoms by applying time-dependent perturbation theory. It discusses the origins of fine and hyperfine structure as perturbations representing relativistic effects and interactions of electrons with atomic nuclei. Using degenerate perturbation theory, you’ll study interactions between atoms and static electric and magnetic fields.

Part 2
The second part examines the application of quantum mechanics to the complex many-electron systems of atoms and molecules. Topics in many-electron atoms include the central-field approximation and the periodic table, spin-orbit coupling and spectroscopy. It then discusses the quantum mechanics of many-electron states in molecules. We also expect to cover the electronic structure of diatomic molecules, the quantum mechanics associated with the rotation and vibration of diatomic molecules, and their molecular spectra.

Part 3
The final part introduces the statistical mechanics of matter. A review of thermodynamics and statistical mechanics includes an overview of canonical ensembles. The statistical mechanics of Bose and Fermi gases (i.e. quantum gases) follows. You’ll study metals and ultracold gases, leading to a discussion of Bose–Einstein condensation. The module finishes with a discussion of critical behaviour, where interactions lead to phase transitions. You’ll also study van der Waals gases and spin systems, with the phenomenological theory of phase transitions applied to magnetic materials and other systems.

You will learn

The main aim of this module is to develop your advanced understanding of physics and expand your reasoning and problem-solving through the teaching of quantum and statistical mechanics.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • marking your assignments (TMAs) and providing detailed feedback for you to improve
  • providing individual guidance, whether for general study skills, specific module content or additional learning resources.

The module has a dedicated and moderated forum where you can join in online discussions with your fellow students. There are also online tutorials. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Assessment

The assessment details can be found in the facts box.

The first and last TMAs plus the examination assess Parts 1 and 3. The second TMA assesses Part 2.

Course work includes

3 Tutor-marked assignments (TMAs)

Additional costs

Study costs

There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.

Ways to pay for this module

We know there’s a lot to think about when choosing to study, not least how much it’s going to cost and how you can pay.

That’s why we keep our fees as low as possible and offer a range of flexible payment and funding options, including a postgraduate loan, if you study this module as part of an eligible qualification. To find out more, see Fees and funding.

Study materials

What's included

You’ll have access to a module website, which includes:

  • a week-by-week study planner
  • course notes and other module-specific materials guiding you through the text books
  • video lectures summarising the module units
  • exercises and solutions to aid your understanding of the concepts and improve your skills and techniques
  • assessment details and submission section
  • online tutorial access
  • access to online forums.

We’ll provide the electronic textbook Topics In Statistical Mechanics by Cowan. You’ll need to buy a copy of Physics of Atoms and Molecules by Bransden and Joachain.

Computing requirements

You’ll need broadband internet access and a desktop or laptop computer with an up-to-date version of Windows (10 or 11) or macOS Ventura or higher.
