Swansea University

What you'll study

The programme develops a rigorous grounding in the fundamental principles of physics together with the advanced mathematical tools used to formulate and solve physical problems. Teaching combines lectures, problem classes, computing laboratories and a substantial individual research project in the final year.

• Year 1 (foundation): core modules usually cover calculus and linear algebra for physics, classical mechanics, electromagnetism, introductory quantum mechanics, and laboratory skills. Emphasis is placed on developing mathematical technique and computational literacy.
• Year 2 (core topics and methods): builds on the first year with more rigorous courses in mathematical methods for physicists, intermediate quantum mechanics, statistical mechanics and thermodynamics, electrodynamics, and computational physics. Students may begin selecting optional modules in areas such as condensed matter, particle physics or relativity.
• Final year (advanced topics and project): focuses on specialised theoretical topics such as quantum field theory, general relativity, many-body theory and advanced statistical physics, together with a substantial independent research project or dissertation under academic supervision. Advanced computational and analytical techniques are applied to current problems in theoretical physics.

Entry requirements

Entry is competitive. Swansea looks for strong achievement in school qualifications, with a solid background in mathematics and physics. Typical applicants hold A-levels (or equivalent) including A-level Mathematics and A-level Physics, or an appropriate mathematics-based qualification. International equivalents such as the International Baccalaureate, Scottish Highers, or recognised international qualifications are also accepted.

Applicants with non-standard backgrounds may be considered if they can demonstrate adequate preparation in mathematics and physical sciences. All applicants must meet the university's general admission and English language requirements.

Career prospects

A BSc in Theoretical Physics provides a highly transferable skill set: advanced quantitative reasoning, mathematical modelling, programming and problem-solving. Graduates move into a wide range of careers including academic and industrial research, postgraduate study (MSc/PhD), finance and quantitative analysis, data science and machine learning, software engineering, technology and engineering roles, and teaching.

The programme also prepares students for careers in national laboratories, government research, and companies that require strong analytical and modelling expertise. Many graduates combine further study with industry placements or research positions to specialise in areas such as condensed matter theory, particle physics, computational modelling or finance.

Why study at Swansea University

Swansea University combines a research-active physics department with supportive teaching and good access to computing and laboratory facilities. The university has active research groups in areas linked to theoretical physics, such as condensed matter, quantum materials and computational modelling, providing opportunities for final-year projects and collaboration with research staff.

Students benefit from small-group problem classes, personalised supervision for projects, and opportunities to develop programming and numerical skills that are highly valued by employers. The campus environment and links with regional and national research centres provide options for placements and collaborative research projects during the degree.
