About this position

PhD opportunity at Cardiff University in Physics and Astronomy on search for quantization of space-time with photon counting interferometry.

This project sits in the Gravity Exploration Institute (GEI) and is led by Prof Hartmut Grote. It combines precision laser interferometry, single-photon detection, optical filter cavities, feedback control, and data analysis to test whether space-time is quantized. The work is experimental and also includes computer simulations. The broader SPI-QG project will integrate the filter cavities into two 7.5 m Michelson interferometers, building a new instrument for fundamental physics.

Research themes include quantum gravity, optical physics, experimental physics, particle physics, gravitational-wave astronomy, dark matter, and searches for very-high-frequency gravitational waves. The group notes that it is a diverse team embedded in a world-leading gravitational-wave astronomy environment.

Funding: This is an EC fully funded studentship for 3.5 years, covering full tuition fees and a UKRI standard stipend of £21,805 for 2026/27. It is open to both UK/home and international candidates, and international students will not pay the UK/international fee difference.

Eligibility: Applicants should have or expect a first-class or good 2.1 degree in Engineering, Physics, or a related subject. Non-native English speakers normally need to meet Cardiff’s English language requirements (example given: IELTS 6.5 overall with 5.5 minimum in sub-scores).

How to apply: Apply through Cardiff University’s postgraduate research portal for the Doctor of Philosophy in Physics and Astronomy. In the research proposal section, include the project title and supervisors and paste the project description. Upload your CV, transcripts, certificates, and personal statement, and arrange for two references to be emailed to the department.

Deadline: The post says applications will be reviewed after the deadline and may close early if a suitable candidate is found. The source page shows Friday, October 30, 2026.

What's required

Applicants should hold or expect to gain a first-class degree or a good 2.1 (or equivalent) in Engineering, Physics, or a related subject. Non-native English speakers are normally expected to meet Cardiff University minimum English language requirements, e.g. IELTS 6.5 overall with 5.5 minimum in sub-scores. Applicants should submit a CV, degree certificates and transcripts, a personal statement/covering letter, and two references; the personal statement should explain research interests, preparation, and why the project is important.

How to apply

Apply for the Doctor of Philosophy in Physics and Astronomy starting 2 January 2027 (late start up to October 2027 possible). Submit the Cardiff University postgraduate research application, upload your CV, transcripts, certificates, and personal statement, and include the project title and supervisors in the Research Proposal section. Ask referees to email references to [email protected].
