Course Overview

Theoretical Physics combines analytical reasoning and problem solving using the language of mathematics to understand the universe. Our degree schemes are for those with a deep desire to understand how everything works, from the subatomic quantum world to the vastness of the cosmos. 

We are proud of our research at the frontiers of theoretical physics. We strive to inspire the next generation of theoretical physicists with an exciting environment for learning and research. Our curriculum is shaped by world-leading experts across a wide spectrum of research areas, ranging from semiconductors, nanophysics and lasers, to the physics of antimatter, quantum fields and the early universe. Our courses equip students with analytical and problem-solving skills, and have wide ranging applications which cut across disciplines.

A highlight of all degree schemes is the opportunity to work on advanced projects, often at the cutting edge of physics research, under the supervision of internationally-recognised academics. Our extensive network of research collaborations, including at large-scale facilities such as CERN, give exciting project and research opportunities for students and researchers alike.

This programme is also available as a 4-year MPhys, which is an advanced undergraduate degree, adding a further research-focused year to your degree. Our MPhys leads to a master’s level qualification, in addition to your undergraduate degree, giving you expert scientific training and a springboard towards a range of specialist careers.

Why Theoretical Physics at Swansea?

The Physics department at Swansea is a highly regarded department, with internationally renowned academics.

  • Top 201-250 in the world (QS World University Rankings 2025)
  • UK Top 20 for Student Experience (Times Good University Guide 2026) 
  • 97% of Physics graduates are in employment and/or study, or doing other activities such as travelling 15 months after leaving Swansea University (Graduate Outcomes Survey 2025)

Your Theoretical Physics Experience

As a theoretical physics student at Swansea, you will join a friendly, supportive, and active community. Much of student life centres around the shared social and study space known as the Event Horizon on the sixth floor of the Vivian Tower. It is a popular place to meet friends, work together on problems, or simply relax. The space also hosts regular social activities, including the weekly tea and coffee sessions run by the student led Physics Society, Physoc.

Your curiosity will be supported both inside and outside the classroom. Throughout the year, you can take part in seminars, guest lectures and trips to research facilities. The Department regularly welcomes world leading speakers, including Nobel Prize winners, as part of the annual David Olive Distinguished Lecture series. These events are open to all students and offer a valuable chance to hear about cutting edge research and the real world impact of physics.

You can also get involved in Physoc’s trips to major research centres such as the Diamond Light Source and CERN. These experiences allow you to see physics in action at world class facilities and can inspire future career ideas.
To help you settle into university life, you will be assigned a Personal Tutor at the start of your studies. Whenever possible, you will keep the same tutor throughout your degree, allowing you to build a trusting and supportive relationship. Tutors take a mentoring approach, helping you set goals, reflect on your progress and access support when you need it. You will meet regularly each semester, but tutors also operate an open door policy so you can reach out at any time if you face challenges that may affect your studies.

Together, these opportunities create a welcoming and stimulating environment where you can grow academically, make friends for life and feel part of a vibrant physics community.

This course also offers you the opportunity to spend a Year in Industry, in the UK or overseas, enabling you to gain valuable workplace experience. The University advocates for paid-only placements, which on average have a salary of over £20,000. Unpaid placements are considered on a case-by-case basis.

This programme is also available as a 4-year MPhys, which is an advanced undergraduate degree, adding a further research-focused year to your degree. Our MPhys leads to a master’s level qualification, in addition to your undergraduate degree, giving you expert scientific training and a springboard towards a range of specialist careers.

Theoretical Physics Employment Opportunities

Throughout your degree, you will develop the skills and confidence needed to succeed in a wide range of careers. Career preparation is embedded across all years of study. Careers fairs and employer events give you the chance to meet organisations who value the skill set developed through a physics degree.
You will have access to Swansea University’s Careers and Employability Team, which offers advice on applications, interview preparation and job searching. Within the Department, an Employability Champion shares careers information and supports you throughout your studies. Our annual Physics Employability event connects you with alumni who talk about their career journeys and the many options open to physics graduates. 

Your final year independent research project will help you develop advanced problem solving, planning and communication skills. You will learn how to manage complex tasks, work independently and present your findings clearly, skills that are highly valued by employers across many sectors. If you are studying on the MPhys pathway, you may also have the chance to work as a demonstrator in laboratory and workshop classes, gaining mentoring and leadership experience.

Physics graduates progress into a wide range of careers. Many work in areas such as:

  • Information Technology
  • Data Science
  • Financial Modelling
  • Engineering
  • Software Development
  • Medical Physics
  • Systems Engineering
  • Research and Development
  • Teaching
  • Management Consulting

Graduate Outcomes data also shows that physics graduates command strong salaries across the sector. Some students choose to continue their studies, and a significant proportion of those in further education go on to PhD programmes.

Whether you want to pursue a scientific career, move into industry, or explore opportunities in business, finance or technology, the skills you will gain on this programme will equip you for a successful and flexible future.
