Theoretical Physics

7th in the UK for our research environment in Physics in REF 2021 (Times Higher Education)

About the course

If you want to use your mathematics skills to explore the concepts of fundamental physics, this course is for you.

Alongside mathematics, you’ll learn the methods of theoretical physics, and apply them to areas such as particle physics, cosmology, and condensed-state and atomic physics. This focus means that you’ll spend less time on experimental techniques compared to other physics courses.

You’ll be taught by our world-leading researchers who are at the forefront of physics. Their work includes:

- developing next-generation quantum computing devices

- using the ATLAS detector at CERN

- studying our universe using the James Webb Space Telescope.

This work informs your teaching – our modules are based on the latest faculty research. Topics may include:

- lasers and photonics

- perturbation theory

- quantum mechanics

- stellar and planetary physics

In your third year, you’ll join a research team for your final-year project. From sustainability to economics and modern languages, you take electives from other subjects to open your mind to other disciplines and tailor your degree to your interests. You can also apply for a year studying abroad or going on a placement.

By graduation, you’ll have gained the skills employers are looking for. You’ll be skilled in Python programming, transforming physics problems into mathematical statements and statistical analysis.

Accreditation
