About the Project

We have developed methods and tools to understand the spin dynamics of molecules that are now mature enough to use in the design of new materials. We would now like to extend use of these tools to study the spin dynamics in solid state materials. That is, we aim to determine the strength and implications of spin-phonon coupling in the most promising solid-state impurity qubit candidates including nitrogen-vacancy (NV) centres in diamond, silicon-carbon divacancy centres in silicon carbide, and cerium impurities in yttrium aluminium garnet, for example.

 Obtaining atomic-scale information on these systems will enable reduction of deleterious extrinsic factors that are currently limiting the applicability of such materials. For instance, the nature of the surface chemistry of diamond in proximity to NV centres is known to limit phase coherence times, so understanding how different surface treatments affect coherence is vital for increasing the sensitivity of NV-based quantum sensors.

Applicants should have or expect to achieve at least a 2.1 honours degree in Chemistry or Physics

Equality, diversity and inclusion is fundamental to the success of The University of Manchester, and is at the heart of all of our activities. We know that diversity strengthens our research community, leading to enhanced research creativity, productivity and quality, and societal and economic impact. We actively encourage applicants from diverse career paths and backgrounds and from all sections of the community, regardless of age, disability, ethnicity, gender, gender expression, sexual orientation and transgender status.

 We also support applications from those returning from a career break or other roles. We consider offering flexible study arrangements (including part-time: 50%, 60% or 80%, depending on the project/funder).
