DPhil in Atomic and Laser Physics

About the course

The department researches the interaction of light and matter over an enormous range of conditions, from high-energy plasmas created by the most powerful lasers in the world, to the coherent manipulation of single quantum particles for implementing quantum information processing, to the creation of exotic states of quantum matter such as Bose-Einstein condensation.

Research in atomic and laser physics (ALP) involves some of the most rapidly developing areas of physical science and ranges from the fundamental physics of quantum systems to interdisciplinary application of lasers. The themes include the following, using both experiment and theory:

  • quantum computation
  • quantum cryptography
  • quantum chaos
  • quantum memories
  • optical manipulation of cold atoms and molecules
  • ultra-cold matter
  • Bose-Einstein condensations
  • optical lattices and quantum simulations
  • ions traps and entanglement
  • non-linear optics
  • cavity quantum electrodynamics
  • quantum optics
  • high-intensity laser interactions
  • ultra-fast X-ray science
  • laser-plasma science
  • attosecond optics
  • optical metrology and precision spectroscopy
  • fundamental tests of QED
  • femtosecond combs
  • EPR and NMR for QIP
  • laboratory astrophysics

At graduate level, the department primarily offers the DPhil research degree (equivalent to a PhD). In very exceptional cases, it may be possible to do an MSc by Research in Atomic and Laser Physics. There is no graduate taught master’s course in ALP. 

The DPhil is a research degree and you normally start working on your main research project as soon as you arrive. A list of current projects is available on the ALP website.

In parallel with your project, you will be expected to attend a taught course in atomic and laser physics in the first year, comprising lectures, seminars and discussion classes at graduate level. Depending on your level of knowledge, the department may also require you to attend lectures in the final year (master’s-level) undergraduate course at Oxford. Continuation beyond the first year is dependent on successful participation in the graduate course and on original research documented by a written report. Examination of the research element is by viva at the end of the first year.

The ALP sub-department provides a detailed timetable and syllabus list for the graduate class. Topics covered include:

  • basic light-matter interaction
  • photonics and quantum optics
  • laser-plasma interactions
  • quantum information processing and communication
  • trapped particles and quantum gases
  • high energy density science

Some subjects, such as laser-plasma interactions and high energy density science, are taught across a number of sub-departments. 

In addition, the sub-department's journal club focuses on recent research highlights in atomic and laser physics, quantum technologies, and laser-plasma interactions. Active participation is compulsory for first year graduate students. Many other opportunities exist to attend training courses outside the sub-department.

Supervision

For this course, the allocation of graduate supervision is the responsibility of the Department of Physics and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff. Under exceptional circumstances, a supervisor may be found outside the Department of Physics.

Graduate destinations

A large number of former ALP graduate students now pursue careers in either academia or industry, predominantly focusing on research and development.

Changes to this course and your supervision

The University will seek to deliver this course in accordance with the description set out in this course page. However, there may be situations in which it is desirable or necessary for the University to make changes in course provision, either before or after registration. In certain circumstances, for example due to visa difficulties or because the health needs of students cannot be met, it may be necessary to make adjustments to course requirements for international study.

Where possible your academic supervisor will not change for the duration of your course. However, it may be necessary to assign a new academic supervisor during the course of study or before registration for reasons which might include sabbatical leave, parental leave or change in employment.

Entry requirements for entry in 2020-21

Proven and potential academic excellence

Degree-level qualifications

As a minimum, applicants should hold or be predicted to achieve the equivalent of the following UK qualifications:

  • a first-class or strong upper second-class undergraduate degree with honours in physics, mathematics or related fields. The equivalent of a UK four-year integrated MPhys or MSci is typically required. Bachelor's degrees with a minimum four years' standard duration may also satisfy the entry requirements.

Entrance is very competitive and most successful applicants have a first-class degree or the equivalent. In exceptional cases, the requirement for a first-class or strong upper second-class undergraduate degree with honours can be alternatively demonstrated by a graduate master’s degree or substantial directly-related professional or research experience.

For applicants with a degree from the USA, the typical minimum GPA sought is 3.3 out of 4.0. However, selection of candidates also depends on other factors in your application and most successful applicants have achieved higher GPA scores. 

If your degree is not from the UK or another country specified above, visit our International Qualifications page for guidance on the qualifications and grades that would usually be considered to meet the University’s minimum entry requirements.

GRE General Test scores

Supporting documents 

You will be required to supply supporting documents with your application, including references and an official transcript. See 'How to apply' for instructions on the documents you will need and how these will be assessed.

Performance at interview

Interviews are normally held as part of the admissions process.  

After the deadline the applications are looked at by potential supervisors (either those named by the applicant or another supervisor may show interest in the candidate). The Graduate Admissions Committee meet to discuss all the applications which ends with an interview list. Candidates and potential supervisors are canvassed for dates/times when the interview can take place. Where possible these are face to face; however, Skype interviews will be held for overseas candidates.

A formal interview will be held, usually with three academics present (at least one representative from the Graduate Admissions Committee). The interview lasts 30 minutes which includes a 10 minute presentation on a subject of your choice, eg a practical scientific work project that you have carried out as part of your course or a vacation project, a part of your course work or a theoretical topic that you found interesting. You should be prepared to answer questions on your presentation. The committee will also ask you questions about your current undergraduate studies and what your plans are for the future. After the formal interview you will visit group heads in the areas of research in which you are most interested, to discuss the research project(s) on offer and be shown around the department (time permitting).

After the interview you will be asked to provide a list in order of preference of the supervisors and research projects for which you wish to be considered. You will be notified, in writing, of the outcome of your interview as soon as a decision has been made.

Supervision

Any offer of a place is dependent on the University’s ability to provide the appropriate supervision for your chosen area of work. Please refer to the ‘About’ section of this page for more information about the provision of supervision for this course.
