Superfluidity is one of the most remarkable consequences of macroscopic quantum coherence in interacting condensed matter systems and manifests itself in several fascinating effects. This includes dissipationless flow of a superfluid and the formation of vortices with quantised circulation. First observed in liquid Helium in 1937, it is closely related to Bose-Einstein condensates and to the phenomena of superconductivity that arises in some materials.

In recent years, new techniques have been developed that have led to the direct experimental visualization of vortices in superfluids as reported in recent articles published in Nature/Science [Bewley et al. (2009), Gomez et al. (2014)]. New experiments are now being planned by different research groups that will use new types of particles to tag these vortices. These particles consist of exotic ion states that produce bubbles within the superfluid. Modelling the motion of these ions trapped within the bubbles and their interaction with the vortices will be essential in helping to interpret results to be obtained from these experiments. Exotic ions in these systems promise to reveal, for the first time, new direct evidence of novel vortex dynamics.

The primary tools to tackle the project will be a combination of theory and numerical simulations. Topics that are relevant to the described research include, fluid mechanics, quantum mechanics, nonlinear waves, numerical methods, and statistical mechanics. The successful candidate will join an active and thriving research group working on the modelling of superfluid phenomena. The successful candidate will also have the opportunity to interact with several other research groups. This PhD project will place you at the frontier of a fast-moving new subject, which promises many exciting career opportunities.

Interviews will be held w/c 22 January 2018.

Funding notes

This PhD project is in a Faculty of Science competition for funded studentships. These studentships are funded for 3 years and comprise home/EU fees, an annual stipend of £14,553 and £1000 per annum to support research training. Overseas applicants may apply but they are required to fund the difference between home/EU and overseas tuition fees (in 2017/18 the difference is £13,805 for the Schools of CHE, PHA & MTH (Engineering), and £10,605 for CMP & MTH but fees are subject to an annual increase).
