Postdoctoral researchers in condensed-matter atomic clocks

We are seeking one or more researchers to develop a condensed-matter atomic clock. They will join a new and ambitious effort, in collaboration between Lancaster University and LocatorX, Inc., 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. The aim of this project is to advance the technology readiness of the device from TRL3 to TRL5. To do this, we will construct and characterise a table-top prototype clock, then 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 partner to this project, and its importance.

This project takes advantage of newly purchased equipment and recently renovated lab space, and forms part of the research cluster centred on the Quantum Technology Centre. For more information about the group and this research area, see http://wp.lancs.ac.uk/laird-group/. For informal enquiries, contact Prof. Edward Laird (e.a.laird@lancaster.ac.uk).

The closing date is currently 6 November, but will be extended if necessary.
