PhD Studentship: Redefinition of SI Second Using Optical Clocks University of Birmingham in United Kingdom

[Fully funded PhD studentship.]

This fully funded PhD studentship at the University of Birmingham offers an exciting opportunity to contribute to the redefinition of the SI second using state-of-the-art optical clocks. Optical clocks represent the pinnacle of precision measurement, surpassing traditional microwave clocks by orders of magnitude. The current definition of the SI second relies on the cesium hyperfine transition in the microwave domain, but advances in optical clock technology have prompted a global effort to redefine the SI second based on optical transitions.

As a PhD student, you will join a dynamic research group engaged in developing and comparing ensembles of optical clocks, both stationary and transportable, as part of a collaborative network spanning the UK and Europe. The project involves experimental work in atomic physics, quantum optics, and precision instrumentation, with applications in fundamental physics and international timekeeping standards. You will work alongside experienced postdoctoral researchers and fellow PhD students, gaining hands-on experience with cutting-edge laboratory equipment and techniques.

The position is fully funded, covering tuition fees and providing a stipend. Applicants should have a strong background in physics or a closely related field, with a keen interest in experimental research and precision measurement. The ability to work collaboratively and communicate effectively within a multidisciplinary team is essential.

The application deadline is 16 April 2026. Prospective candidates are encouraged to apply online via the University of Birmingham portal and may contact Professor Yeshpal Singh ([email protected]) for further information about the project and application process. This studentship is ideal for those passionate about advancing the frontiers of timekeeping and metrology through innovative research in optical clocks.
