Research Assistant/Senior Research Assistant/Research Fellow in Condensed-matter Atomic Clocks

(Full time, indefinite with end date)

We are seeking a researcher to develop a condensed-matter atomic clock. They will join a new and ambitious effort, in collaboration between Lancaster University, Teleplan Forsberg Ltd, and LocatorX, Inc., with funding from Innovate UK, to apply new developments in electron spin resonance to clock technology.

The project exploits spin resonance in nitrogen endofullerene molecules, whose spin states possess long quantum coherence times and therefore a well-defined transition frequency even at room temperature. We have discovered a clock transition in this material, meaning that the frequency (unlike that of most spin resonance transitions) is insensitive to magnetic-field fluctuations. This is the key discovery that underpins this technology, and we have used it to create a tabletop clock. The aim of this project is to advance the technology readiness of the device from TRL4 to TRL5, and to miniaturise the physics package. To do this, we will incorporate new techniques to stabilise and track the transition frequency even under environmental perturbations such as fluctuations of magnetic field and temperature. We seek experimental physicists with knowledge of spin resonance and electronic measurements who are motivated to use fundamental physical principles to create a new technology.

Precision timekeeping is essential for navigation, communication, and radar. An atomic clock that is small, low-power, and cheap will have many important applications in these fields. However, existing clocks based on atomic vapours contain optical and vacuum elements that are difficult to miniaturise further. This is an exciting opportunity to develop a new class of clock by drawing on rapid scientific progress and on strong technology pull from a committed industrial collaborator. Depending on the candidate, the appointment may be made up to the level of Research Fellow, i.e. above the usual grade for postdoctoral researchers. This reflects the commitment of our industrial partners to this project, and its importance. A part-time appointment may be possible for a suitable candidate.

You will join us on an indefinite contract. However, the role remains contingent on external funding, which at this time runs until approximately November 2026 (depending on start date and appointment grade).

This project takes advantage of newly purchased equipment and forms part of the research cluster centred on the Quantum Technology Centre. For more information about the group and this research area, see wp.lancs.ac.uk/laird-group.

Informal enquiries can be made to Prof. Edward Laird (e.a.laird@lancaster.ac.uk). It is anticipated that the appointment will be made from October 2025 or soon afterwards.
